st: To calculate F tests

[Claude Francoeur <claude.francoeur@hec.ca>]

Hello,

I need to calculate F values to compare a series of about 20 restricted and 
unrestricted least-squares regressions.  What is the command to store (or 
retrieve) the RSS values of the regressions in order to calculate the F 
value after each set of regressions (restricted and unrestricted)?

Thank you!

Claude
