Subject:      normality of residuals: opinions?
Content-Type: TEXT/PLAIN; charset=US-ASCII

Sorry to burden the listserv like this, but I wanted to get a second
opinion concerning the distribution of residuals from a REG procedure
regression.  The question before me is whether I should log transform the
IV.  The data follow my signature.

Thank you,

Kevin
