When a gamma distribution is specified in SAS, does SAS perform a log transformation to achieve and satisfy the data normality assumption? I thought using a gamma distribution violates normal assumptions. @Rick_SAS
Thanks,
The normality assumption does not apply to a generalized linear model using a distribution other than the normal distribution. See this note.

Thanks. I am trying to edit this statement and thinking of knocking out the second part.
I would like to clarify if this is a valid statement or not: " A gamma distribution was used for all data analyses, for which a log-transformation was conducted by SAS to achieve data normality."
