Moving Average

I have a table called drugs with columns drug and result, how do I calculate the moving average of the result column by taking the first 4 rows followed by the next 4 rows and similarly continue. Pfa the sample table for reference. 

Re: Moving Average

JMP's support documentation gives some additional background for how the formula may be defined (defines the arguments and also includes some nice little examples):  https://www.jmp.com/support/help/en/16.2/#page/jmp/statistical-functions-2.shtml#

 

 

You can find in Wikipedia (https://en.wikipedia.org/wiki/Moving_average) more on first principles and mathematical/ conceptual understanding behind the Moving Average Calculation:

 

 

Re: Moving AverageThanks this workedRe: Moving Averagewhat does weighting = 1, before = 3, :Drug mean?
Could you please explain the formulaRe: Moving Averagethis did not work
Re: Moving Average

I think this will give you the moving average that you want (4 rows before and 4 rows after).

Re: Moving Average

The formula to use is

If( Mod( Row(), 4 ) == 0,
 Mean( :Result[Index( Row() - 3, Row() )] )
)

I have attached your example data table, with a new column with the formula in it

Re: Moving Average

I want to generate the moving average column as shown in the attached table, for every 4 rows I need to calculate the average

Re: Moving AverageDo you have 4 columns of results, or 4 times as many rows as you show in your sample data table?Re: Moving AverageCould you please explain the next step after this, I want to calculate the average of 4 consecutive samplesRe: Moving Average

Create a new column in your data table, and apply the folloing formula

Col Moving Average( :Result, weighting = 1, before = 3, :Drug )

Re: Moving Average

hello ,

you can try with Formula column --> row --> moving average

 

Re: Moving Average

Thanks Jim!

 

Just used this method to calculate the difference between the maximum and minimum for the last n rows.

Hope you are doing well!
