Rolling Standard Deviation Webi Formula

Hi,


I need some help in creating a rolling Standard Deviation for 20 days at one time. So for Example the date is 02/02/18 I want to get the standard Deviation of the values between 02/02/18 and 01/05/18.

I have attached a spreadsheet of how it has been done in excel i just need to calculate the column in yellow.

Thanks,
Ryan

    Hi,

    Do you have any range of dates that user enters as a prompt or selection criteria?.

    you can use Daybetween() to get number of days.

    Thanks,

    Hi,

    No there is no prompt so Daysbetween() wouldn't work as i am trying to do a rolling calculation.

    Thanks,
