Greetings,
I have performed an analysis using a non-SAS program on the members of
21 pedigrees. My outcome variable was FVIII.
My plot of the residuals (FVIII - FVIII_predicted) versus FVIII appears
to suggest a correlation, i.e. subjects with a high FVIII have larger
residuals and those with low FVIII have smaller residuals. This concerned
me. Is my concern warranted? The residual plots versus two independent
variables appears random, as I expected.
Thanks,
Kevin
