Assumption of Discriminant Analysis


New Member
Hi, there. I have a problem.
I want to compare 3 categories of fish with 20 variables using discriminant analysis.
The question is about normality test.
1. Should I check the normality data? If yes, should check in all IV using the DV or only in IV?
2. What should I do, if the data is not normal? Becuase the Sig is 0,00
Please help. Thank you
