Hi!
If I take the "amount of a credit" as a variable for my logistic regression,
tests for normality aren't ok.
Indeed, people don't ask for small amounts of money, so that the
distribution has a tail on the right and is equal to 0 in the small values.
Question :
Do i have to transform the variable before computing?What are the common
transformations ?(in this case and generally : log?sqrt?...)
Thanks a lot.:)
