I have daily streamflow data for a large number of years. One column is the date and the second column is the streamflow value. I want to compute the maximum value and the 3-day maximum (largest average value for any consecutive 3-day period)for each water year (starts on October 1 and ends on Sept 30). Of course the number of days each year varies by one during leap years.

I am trying to find a way to locate multiple local minima/maximas from my data. My chart essentially looks like a straight horizontal line with multiple, small spikes pointing downwards. I'd like to be able to locate the position of these minima easily.
determining a formula to compute a sales commission.
Here is a sales scenario.
A $25 commission will be paid on sales between $50 to $150.
A $50 commission will be paid on sales between $151 to $300
A $75 commission will be paid on sales between $301 to $600
The sales person will enter the sale amount into column B. Column C should compute the total commission for multilple sales.
Example:
Column A Column B
Sales Commission
$50 $150 (which is the comm. for the combined sales)
$175
$360
computing the number of business hours between 2 dates.
Given the following information:
- Business Hours: 8am -5pm (8:00-17:00)
- Business Days: Mon-Fri
- if entry queued falls on a weekend or beyond the business hours, it should count the first hour on the next business hour.
Example: scenario 1 = Starts Sunday, 10am and Ends Monday 9am; count of hours should be 1
scenario 2 = starts on Monday 6pm and ends on Tuesday 10am; count of hours should be 2
Im looking for an Excel macro that will allow me to input any date and time and produce x,y,z co-ordinate results for planetary positions relative to the centre of the universe. I already have a database with ephemeris data but find it difficult to use manually inputting date and time constantly. I need to perform so many calculations that automating this procedure is essential to me but i dont know how.
View 2 Replies View RelatedMy spreadsheet opens. Cell A1 determines what today is, formatted as "weekday, day month year" (e.g., "Tuesday, 18 February 2014").
I have another cell in which I typically enter the date for the coming Friday. Instead of updating this field once each week, I'd like to calculate the date for the next coming Friday based off the value in cell A1 (to be concise, if "today" happens to be a Friday, then it would calculate the date of next Friday). (Continuing the example above, the coming Friday would be computed as 2/21/2014. If I open the spreadsheet on 2/21, it would calculate 2/28.)
What formula or step(s) to follow to render this value automatically?
Using Excel 2003, Column E has a varying and unpredictable number of rows, which only the final 252 rows are of significance. I need to compute the following formulas, here written in English as I can't determine the proper terminology to accomplish this task in Excel:
Final Row with a number in Column E/average (final 252 rows with numbers in column E)+
Final Row with a number in Column E/average (final 126 rows with numbers in column E)+
Final Row with a number in Column E/average (final 63 rows with numbers in column E)
Once again, what makes this not straightforward for me is the column may have wildly varying numbers of rows.
I am trying to set up a spreadsheet that will have a calculator where variables can be modified in order to properly see staffing requirements using the Erlang C formula. I have all of the known variables, but I can't seem to figure out how to calculate the formula to get the numbers I'm expecting.
[URL] is the website I'm using currently, and I'm stuck at the actual Erlang C formula. I'm not very good at math, but here is how I am reading the formula in English (I'm using the given numbers on the site for the variables so I can check my work).
Erlang C = calls per second to the power of agents staffed divided by the factorial of agents staffed. The result is then divided by calls per second to the power of agents staffed divided by the factorial of agents staffed again, that result is added to 1 minus occupancy, that result is multiplied by the summation of 0 to 54 (54 being the result of 55 agents staffed minus 1), which is then multiplied by calls per second to the power of "k" (i haven't yet figured out what k should equal, i assumed zero from the summation) divided by the factorial "k".
The result I get is not even close to what the website shows as the answer for Erlang, which should be .239. Am I making faulty assumptions anywhere? It's entirely possible I'm not computing the formula properly, it's been about 12 years since I've taken a math class, but since I know all the values for the variables (except for "k"), I should be able to write out a simple Excel formula to compute this.
I have to compute monthly standard deviation (volatility) from daily data.
The problem consists on the fact that the days during a month are not constant and change over time.
I attach the excel file : Price_Time_Series.xlsx
In this xls file, you can find dates in column A, price in column B and returns in column C.
I want to compute standard deviation at the end of the month for stock returns (column C), by considering all available days.
As you can note from the file, the days change over time and they are note constant. How can I compute standard deviation of them?
I'm using excel 2007 for analyzing my students grades. I ran two exams and look for a way to compute a final grade score, which should be equal to the grade of the first exam for those students who took just the first exam and should be equal to the second score for those students who took the second exam. (Clarification: for those students who took both terms, their final grade should be equal to their score in the second term).

There are two tabs in my workbook right now. The first is where users will input information and annual budget number for consulting fees. The second tab spreads the annual budget by the 12 months. I don’t want the users to see or touch this tab containing the spread. Once the annual budget number is entered, I would like them to use a combobox to choice how they would like to spread the budget monthly. One choice is evenly which is the default and the other would be manually. If they choice manually I would like a userform or something where they than input each month’s amount that will total the annual budget. See attachment, this is all I got so far.
View 2 Replies View RelatedI'll try to be as concise yet informative as possible. In the included attachment you will find a list of names in column A. These names have each have an event that is due at the end of his/her month, once annually. The due month for each person is listed in column B. Once that person completes the event, it is recorded in column C. The event will then not be due until the following year by the end of their due month.
I need column D to reflect the last day of their due month.
This date will change once the event is completed and recorded in column C. There are of course a few additional requirements that puts this out of my ability. They are listed below:
The person may complete the event at any time within three months of their due month. So if Tom's due month is September, he may complete the event anytime in July, August, or September. This would then need to reset the "Due by" date (column D).
If the person does not complete the event, the original "due by" date should not change until the event is completed.
Last note: this attachment is from Excel for Mac, The actual sheet this will be used on will be windows (so no worries about the formula changes for Mac).

View 5 Replies View RelatedI am trying to calculate the compound annual growth and my starting point is a negative number. The example is that I have (273,000) for the YE 2003 and have Growth to the amount of +767,000 at YE 2006. The formula I have been using for other calculations where the starting point is positive is =POWER(J23/C23,1/O$1)-1. Where J23 = a positive amount and C23 = a positive number. This formula works fine, but when C23 = a negative number the formula does not work and the % does not make sense.

View 5 Replies View RelatedI've put together an annual leave tracker for the department and am trying to make it as automated as possible. It currently consists of two sheets, 'Leave Applications' and 'Leave Tracker 13'.
If you look at the 'Leave Applications' sheet, I wish to be able to take this data to fill the calendar on 'Leave Tracker 13' with either AL or HL to demonstrate whether the day is annual leave or half day leave. This only wants to happen if the leave has been accepted, represented by an 'A' on the 'Leave Applications' sheet. The calendar obviously doesn't have any dates in the cells but I've got around this when it comes to shading in weekends by concatenating the date above and to the left of the cells and assume I must be able to do the same for populating it.
It's also complicated by the 'Leave Applications' consisting of multiple members of staff, though this may be ordered by date.
I have been trying to compile some monthly and annual data from our main sheet to a FY09 sheet (for the fiscal year 2009). The 2 tabs in the uploaded example are the Distribution tab which we use to track the status of every item and the FY09 tab where I need the totals to be calculated for each month as well as the entire year. I have tried several formulas I found while searching the forum but I can not seem to get any of them to work, (I am sure it is because I don't understand them very well).
Since any formulas used will need to be copied 200 or so times, I would really like a VB solution which should also reduce the physical size of the file. I also tried a pivot table but I do not think it will show everything I need.
Basically, I need all the items separated by month on the FY09 tab. Then column 'F' on the Distribution tab needs to be summed up for each item in column 'D' of the FY09 tab for the respective month and multiplied by the respective item price in column'C' with the total value going in column 'E'. Column 'D' and 'E' need to be summed up for each month and cumulative for the entire year. There needs to be an average items and value for each month as well as for the year.

The only information given is the labels needed to be used, such as main heading, date, mileage, petrol, maintenance, registration, insurance, subtotals, averages and main totals. I've designed the spreadsheet with date - subtotal at the top of each column, with total and averages on the left hand side, under all the months (so the answers to both the total and averages would be in each column)

View 6 Replies View RelatedI am trying to figure a formula that will give me a monthly increase with a annual target. Example:
2006 sales were $100,000 and December 2006 sales were $9,000.
For 2007 I would like a 10% increase in sales which means I should end up with $110,000 at the end of 2007.
The formula should figure a gradual sales increase each month until December 2007. I am assuming the business sales trend is upward with no seasonality so that January 2007 should be the annualized increase over December 2006.
.
I have used the formula =100000*((1+.1)^(1/12)-1) which works for 2007, but it gives me a large jump between December 2006 and January 2007 and then a slight increases each month.
I have 200 items that have 22 months of usage information each and need to:
1. In one column, show trend (up or down) based on the 22 months' activity for each item.
2. In another column, show/ forecast how much inventory will be needed for the next 12 months.
What I need is a worksheet which will generate fields from a set of variables (similar to a loan amortization schedule).
I don't know how to write the field code to include the annual percentage rate increase based on that additional input variable.
Input variables would be:
starting rate: (ex: 8¢/kilowatt hour)
starting date: (ex: July 2013)
average kw hours/month: (ex: 1062.5 kw hours)
annual rate increase: (ex: 3% *default 0%)
years to display: (ex: 25 years, *shown in months in fields below)
service months per year: (ex: 12 *default 12)
[code].....
So, data fields below the variables would be blank until these are entered.
Assume I would protect the sheet to avoid messing it up.
this would generate a chart showing rates over time from the fields below.
Also it would generate fields in a summary area to show the rate per year for future years.
Secondary, if there were a way to input actual usage and rates from specific months in the past, that would be useful but not part of this forecast model.
The goal of this model is to forecast electrical costs for residential power users compared to independent solar power generation to 25 years forward.
I want to make this because I am skeptical of the advertised savings that solar installers use to convince clients that their return on investment is so high. I believe their data to be greatly inflated projections.
Using this in comparison with other data such as inflation and wages will allow me to get a very good economic picture of the future of independent solar energy generation and its impact on the average home owner.
