Many Welch's F-tests.
A numerical vector with the dependent variable.
A matrix with the data, where the rows denote the samples (and the two groups) and the columns are the variables. This must be a matrix with the categorical variables as numbers, starting from 1. Welch's F-test is performed for each variable.
A boolean variable; it will return the logarithm of the pvalue if set to TRUE.
For each categorical variable in the x matrix Welch's F test is performed. This is the opposie of
where there are many dependent variables and one categorical variable.
A matrix with the test statistic and the p-value for each predictor variable.
