Modified F-test for heterogeneous error variances
Dear R-help:
Does anyone know of a package in R that will do Welch's modified F-test
for heterogeneous error variances? Are there other statistical techniques
available in R that test the equality of means when homoscedastisity
is violated? 't.test' does this in the pairwise sense when var.equal =
TRUE.
With best wishes and kind regards I am
Sincerely,
