I have a column of data (Column A) and I'd like to build first the Average of the first 20 data points (like in an Excel spreadsheet, cell B21 will contain the average(A2:A21), cell B22 will contain average(A3:A22), and so on... rolling).
I looked up on the internet, but I simply don't know how to start with, I mean, how to name the new array and make it rolling.
Then I will need to calculate STDEV for the same interval, and then Zscore ((Value - Average)/STDEV), but I guess it comes automatic once you made the first part.
I am working on a spread sheet and am trying to use rolling averages of the last 3 months. I am using worksheets for each month with a final worksheet containing the 3 mo. rolling average. I tried using a formula with OFFSET and it worked fine if all the data was in 1 worksheet, but did not work for multiple worksheets averaging to another worksheet in the same workbook.
Could you please supply a formula that will calculate a four week rolling average of column B in relation to the dates in column A? I tried using the average and offset functions but can't quite get it to calculate the correct averages.
I'm looking for some help to create a rolling 12 mth average. To explain better I have added a copy of the part of the sheet to help you understand what I am working with.
What I'm looking for is the 12 mth average to show up in cell c26. I have the mths listed in cell A2-A25 and the data I want averaged is in C2-C25
An additional problems is that I only want the 12 mth avg calculated if data in the next mth is greater than zero. Meaning since this month is Mar-09 (which is already collecting data) I dont want to include Mar-09 data yet. I only want to know Mar-08 to Feb-09 average. Once data is returned to Apr-09 then I want the average to show for Apr-08 to Mar-09 and so on. I dont what is better to use vba code or a formula which ever is easier.
I have data that is linked and is updated automatically. I am trying to use named ranges for the rolling data for each area and my date range is 5 cells using the Today()-5,4,3,2,1. The dates are rolling fine, but I cannot get the data to update, it stays the same from day to day.
look at this and see what my error is? cookies and kudos(no password on the unprotect)
I have an excel sheet setup with several tabs which are organized by work days in a week. (i.e. aug 18, aug 19, aug 20, aug 21, aug22, aug 25, aug 26, aug 27, aug 28, aug 29) Sample file has been included.
I would like to do a rolling total of 1 particular cell (the same location on all the sheets, i.e. cell a2 on all sheets) for the past 4 weeks, and it automatically adjusts itself based on today's date (i.e. today is august 27, it will total everything from jul 30, 31, aug 1, 4, 5, 6, 7, 8, 11, 12, 13, 14, 15, 18, 19, 20, 21, 22, 25, 26.).
Is it possible to do this?
I am not familiar with VBA or Macros, so solutions using either of these will require some detailed explanation for me to understand how to apply them.
One of our govt. agencies requires that I compute the 24-month rolling averages of the daily average input to a manufacturing process. In this instance, the agency is demanding the rolling average since 2003, so there are a fair number of data points involved. The process control computer can provide me the daily data (attached file contains 30 months of data), but cannot compute the 24-month rolling average.
I have several worksheets with thousands rows (independent variables) and hundreds columns (all dependent variables). Each line basically gives me hundreds values for each independent variable - see below: ... C9 39.65 653.95 5.28 163.56 99.56 14.49 ... ... E9 7535.92 21500.56 2835.88 3122.98 7225.34 5371.25 ... ... G9 111568 298021 12940 31645 181797 36996 ... .... ...
I need to know how the values in each row are distributed, and I ideally plot a 2D column graph of the distribution. Is there a way to do that and create/program a macro (with relative button on the workboook) that does it automatically once clicked?
Very often there are outlying values (bigger or smaller by a factor of 1000 or even more), mistakes, which I would like to identify and fix possibly
I need to create a Sum of numbers month to date Rolling. Meaning... if I have a expected number for the month, I need to be able to sum the processed numbers for each day up to the current day excluding any day after the current day.
So the formula would need to sumif the total month numbers UP TO the current day and compare that against the processed UP TO the current day. Month Expected Processed April 1 500 450 April 2 500 450 April 3 400 425 April 4 400 450 April 5 400 April 6 450
See attached for example of what I am trying to achieve. I need a macro which will allow me within excel to roll down within column A a block of the same number for 25 rows, insert a blank row, and then add one to the starting number roll it down 25 rows insert a blank row and so on. I would like to start with the number 031400 and continue until 064300 the leading and trailing zeros are key so I have made column A text field.
formula to input to excel to get the dates rolling down in A cell i want it to go A1(1/1/2014) A2(1/1/2014) then a3(2/1/2014) a4(2/1/2014) a5(3/1/2014) a6(3/1/2014) i have a lot of these dates to put into excel
I am trying to create a formula that looks for the last populated cell, counts 12 cells back and returns an average for all of the cells in that range. I know I have done this before with some combination of INDEX and COUNT, but I can't seem to remember how I did it and my experimenting is not proving fruitful.
Attached is a simplified version of the layout I am working with
I am trying to do is create a total of only the last 90 days of entries from a list of $ amounts. Attached is an example. We are going to start keeping track of our cashiers variances but at the top of the sheet we only want to know what their last 90 days of entries equal.
This would be considered a rolling 90 days, so older variances drop off after 90 days, they would still be left on screen but would not effect the main total.
I am trying to get data from one sheet to another. For example:
You'll notice on my attached workbook I have serveral sheets that I would like to show on the one sheet labeled Rollup. Now i know all i have to do is copy and paste, but I would rather for the data to automatically update on the Rollup sheet.
The YTD 10 column is fine that will change everytime you update each month. I was wondering if there was a formula I could use for the Rolling 12 month Column.
At the moment it is averging from Mar 09-Feb10 which is correct but when it comes to putting in data for Mar 10, the Rolling 12 month column will obviously not change.
Is there a way of moving the formula along one each time you input data into a new month. So when Mar 10 has been entered the rolling 12 month column will pick up Apr-09-Mar-10 then when Apr 10 has been entered the formula will change again to May-09-APr-10?
I have researched and read multiple threads related to graphing rolling averages per month. I've setup my own but I cannot get it to graph correctly. The x axis will be the days of the month ie. 1-31. The y axis is obviously the sales volume. The legend should be a line graph for each individual month sales. I want the graph to reflect the current month and previous 12 full months.
I used the file user rockycj started for another user in a different thread labeled, "Excel Line Chart - 12 month chart moving with dates ". It was very helpful and I'm trying to get this completed before my deadline. If anybody could take a look and let me know, I would greatly appreciate the help. I have attached the file for reference.
I'm trying to have a two week rolling dates, starting on the Monday and continuing until the following Friday, this is fine if static but when the start date is then Tuesday, Wednesday etc the week then includes either the Saturday or Sunday.
From using =TODAY(), how do I populate the next ten working days without including the weekends?
I've got a worksheet that has chronological quarterly data for which I'd like to do a 5-year rolling average. The layout is: Column A = Dates, Column B = Values, and Column C = 5-year Rolling Average. My problem is that I want to exclude zero-values from the averaging calculation. I tried the following:
