So I am trying to make a macro that will update monthly forecast data to what the actual production/consumption data was. The production/consumption numbers come in separate workbooks (i.e. "Jan14", "Feb14") and need to be linked to the 'Book' main file. The path needs to the Jan14 needs to come into the 'Book' file, not just the values. I would like to be able to just have a button above each month that will just automatically load that month's data when it becomes available.

how can i calculate the variance?

i have the upper limit (=MIN(1,(mean+half width))

i have the lower limit (=MAX(0,mean-half width)

i have the mean (avg of all numbers)

i have the t value (TINV(alpha, (n-1)))

i have the half width (t value * SQRT of Var/N)

i just don't know how to get the VAR/N

I am looking to calculate variance across a large data set and would like to know if a macro is possible to calculate for a specific unique cell ID. East, Central, or West and calculate variance across that region.

For instance, in my data set if I have something similar to below. How would I calculate variance in the different regions? Is it possible to automate this process? Also could the Analysis ToolPAk be used instead or in conjunction?

[Code]....

I have inherited a series of data relating to a change in a specification over a period of time and a number of cycles.

See attached.

There is already a chart which shows the data and has an exponential line.

I want to find the value of Cycles where the Average Flash exponential from the chart line is 0.131.

FYI this is to plot deterioration in a piece of tooling, 0.131 being the accepted warning level. If you feel there is a better statistical model to use for that application then I'm all ears!

I have a 52 week rolling forecast that I would like to have displayed in each calendar month that it corresponds to. I have come up with a solution where it does lump the data together into months but it is not a smooth lumping of the weeks as some weeks cross over from one month to the next. Is there a way to lump each week into its respective month. My current solution places in some months 4 weeks worth of data and in other months 5 weeks worth of data. Attached is the spreadsheet that I am using. The tab "Weekly Sales" is the 52 week data which has specified the exact dates on the calendar that that week represents. The "Monthly Sales" tab has the 12 week data which has specified the exact dates on the calendar that that month represents. I've tried SUMPRODUCT but that is giving me 4 weeks in some months and 5 weeks in others.

I currently have the formula =100*B38/C38

This returns the answer $76.67. When I format the column to percentage, it the returns the answer 7666.67%.

How do I get this to read as 76.67%???

I constantly use the following to determine the last row in a worksheet for loop control purposes.

[Code] ......

In my current problem i have a worksheet that has been formatted such that the code above returns a value of ,say 150 where as the actual data stops at say row 34.

If I "watch" the value in Col A I see A34 = "1513(a)" which is valid data and A35 = ""

I can easily cycle through the worksheet and calculate the last used row myself but I am always looking for ways to let "VBA do the heavy lifting" when I can

See xls file. I have this chart and the data labels are percentages instead of the actual value. How did these get that way? Under Chart Options there is a autotext box that is there but if I uncheck it, the data labels go back to the actual dollar value and that autotext box goes away.

I am totally baffeled by this despite serach the help, the internet and this forum. I am sure it is something easy I am missing.

Can some one provide some color on this?

I cut this from a larger book with many tabs because I am not able to send out the entire thing (proprietary).

I am working on a spreadsheet for my farm. I have two sets of data I am working with. A very basic example is below:

What I am trying to do is find the actual median stud fee (i.e. if you had another column with $5000 listed 22 times, $6500 listed 34 times, etc. then you could find the median from there).

Seems like an easy thing, but I'm not sure if an array formula is what I need to use or something simpler. I don't have a lot of data right now (only a page) but will have much more soon.

I am trying to edit the data in the actual pivots rather than editing in the data source. i know there is vba code to enable pivot table editiing. how to enable this

View 14 Replies View RelatedTrying to create a basic pivot table from a CSV file for our users. What I've done in the past is open my CSV and then take the option Insert > Pivot Table to create the pivot table from the open CSV/worksheet. My question here is .... how can I save this .XLS and refresh the CSV data within? Or do I need to use an external data source? I don't want to have to use any drivers. I'd love to be able to just point to a CSV or TXT file on our server and that be that.

For something else I have used Web Query strings to point to .php scripts that send back data in XML format. Is this an option?

Again, the goal is for me to create a pivot table and just have our user's open it up and have current/refreshed data within. We can run jobs overnight or on-demand that update the data source.

Column A has a time (no date)

Column B VLooks-up a value from a separate sheet per country, so it pulls through a the variance [-11 to +13] from UTC (GMT) time dependent on country.

All other data is irrelevant.

Let's say Column C has following formula: A2+B2/24.

This works where the time result (new time) is on the same day, but as soon as it crosses over midnight, it buggers up.

What I'm needing to do is take a list of events (server time/GMT) and convert them to the local time from where the event was triggered based on source country.

I am trying to get my variance percentage to calculate correctly but I am struggling when it comes to one of the value being zero. It works fine for the below example when both the variance and last year figures a zero.

Last Year This Year Variance Percetage

0 0 0 0.00% IF(Last Year=0, "",Variance/Last Year)

0 100 100 0.00% This should be 100%

I'm trying to calculate the variance between planned date & time of arrival vs actual date & time of arrival.

I attach the workbook as am a bit useless at explaining myself....

What I've done is in H14 subtract the actual date of arrival (F14) from planned date of arrival (C14). This result is the only way I could think of dealing with crossing over midnight. As a result I14 should subtract the actual time of arrival (E14) from planned time of arrival (B14):

=SUM(E14-B14,H14)

This method works well when the arrival was later than expected but doesn't work if the arrival was sooner than expected.

finding a way to compare the two budgets i.e 08/09 and 09/10 and if a new cost centre appears in 09/10 it will bring a yes in column G(New cc) and if the Cost Centre already exist in 08/09 it will bring a blank--but in both cases i want a variance in the next column H i.e 09/10 less 08/09.

I need to sum up the batch quantities for a date with variance one...

but it doesn't work... I suspect that I'm using wrong formula, it should be not SUMPRODUCT...

when I tried to use just SUM, it adds all the quantities in the colomn.

=SUMPRODUCT(--(($AB$11:$AB$100)=AK12),--($AG$11:$AG$100=1),($AD$11:$AD$100))

I need a formula that will display a 'yes' or 'no' if the following condition is met:

If the value of cell (L17) is greater than 10% positive variance, then 'YES' else 'NO'.

Currently the value of L17 is 14%, therefore should be a 'YES', however how can I get the following to work:

IF(AND(L17=<0,"NO",L17>10%,"YES"))

I apologise as I know there are too many arguements here but is there a way around this?

View 4 Replies View RelatedI am using the Forecast formula to give me a value from a Linear trend. However I need to limit the resulting value that is displayed within a min and max value. Background: This is to allow me to calculate the amount of bonus someone will earn depending on the Percentages of their target they achieve. The min bonus is 25% when 80% of target is achieved and max bonus is 100% when 125% or greater of target is achieved.

So the Forecast formular works great using the existing values, but i need help limiting the results to between 25% and 100%. I was trying to use a sumif formula to copy the resulting cell but only if the value fell between the 25 and 100%. I've attached the spreadsheet as I think it will highlight what i'm trying to do better than I can explain it.

I try to predict some macro economic statistics but any attempt till now didn't make sense. the attached file. Note: when i used the FORECAST function the predicted values showed an unlogical drop while there seems to be a positive trend.

I'm trying to capture a set of forecast dates in a spreadsheet. We have column 1 = forecast date, column 2 = actual date.

I also have at the top of the sheet (which I will hide when I get the forumula to work), today's date, today's date less 13 days and today's date - 27 days.

In column 3, I want a traffic light system whereby if the date in column 2 is equal to or less than (before) each of the 3 hidden dates it the cell colour will turn green, amber then red..
