How to use linest with variably sized data arrays?
I have a spreadsheet which loads data for two time series from the
database given a start date and end date. I would like to calculate a regression between these two series using linest. The problem is that depending on the start and end date, I might have different size of arrays to enter into linest. The first try was to include the largest possible range of arrays -hoping that linest will ignore empty cells when I am loading fewer data items - but linest does not ignore empty cells. Next I tried linest(resize(range1,datasize,1), resize(range2,datasize,1), 1, 0) But that gives me different results (what?) than if I use linest with the exact ranges. Any ideas? thanks in advance and please ask for clarification - this is my first time posting here. matal |
