Hello Dears.
I have a 2 questions about Discriminant Analysis in R.
1- In "ade4" package I perform this analysis for both quantitative and
qualitative variables using "discrimin" function.
R gives me "Canonical weights/ Loadings" and "Canonical scores" but doesn't
give "*F* or *t *or *X-square *statistic" and "P-value" to determine
effective variables and doesn't give "classification matrix" and
"classification error rate".
2- In "DiscriMiner" package, using "disqual" function, we can do
discriminant analysis for qualitative variables. It is performed for
"insurance" data but has error for other data such as "birds" (in Rmixmod
package) . The error sentense for this data is "Error in svd(Znorm) :
infinite or missing values in 'x'". Why? Should data have special
conditions? Also, this function doesn't give "*F* or *t *or *X-square
*statistic"
and "P-value" to determine effective variables for "insurance" data.
Thanks
Best Regards
