beta estimation

["W Lake" <wlake@xxxxxxxxx>]

Thanks ... I'll check that out

This may help you with setting up your beta estimation workbook either as a
stand alone app or as an integrated module. I use it as an integrated module
... the data calls can access any sheet or workbook.

"... There are four possible optimization criteria: (1) sum of squared
errors, (2) weighted sum of squared errors, (3) sum of absolute errors, and
(4) minimax (minimize the maximum absolute error).  The Solver performs the
appropriate optimization, based on the criterion specified. ..."

Here's the part of the code that you need. It goes "behind" the criteria
selection user form.

Best regards
