Hello,

I have a question about the above measures from regression analysis.

How much does each of the measures (R, R square, and adjusted R square)
depend on the assumption of normality? Or, to put it in different terms, how
much could they divert from the measure stated in the SPSS model table when
the normality test failed? Are these measure then completely unreliable
(random) or is there still a level of confidence?

Best Wishes,
Karl
