R Box'M test for homocedasticity

Question

Hi, I'm trying to replicate a linear discriminant analysis output from SPSS in R, and I'm having difficulties to find a way to perform an m-box test.

The only thing I found was some code posted in a forum, to manually implement the process, but I was wondering if there is nothing for this purpose already incorporated in the language itself.

Answer 1

There is code that can be found with a simple rseek search. It's not typically done because it's very high sensitivity leads to significant p-values that may not mean much.
