I'm trying to run linear regression using the data analysis tool pack. I have a total of 193 rows and need to run a linear regression on different subsets of this data. I tried putting filters as usual and then attempted to run the linear regression but every time I do that the entire 193 is getting selected or close to that number such as 189-190, which is not what I need.
Is there any way to do this? Please let me know, thanks in advance
