Many Welch's F-tests.

1 |

`y` |
A numerical vector with the dependent variable. |

`x` |
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. |

`logged` |
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 ```
ftests,
where there are many dependent variables and one categorical variable.
```

A matrix with the test statistic and the p-value for each predictor variable.
