In `anova`, the F value is calculated by dividing [MSR](https://en.wikipedia.org/wiki/Mean_squared_error) (mean of ΔDeviance) with mean of [RSS](https://en.wikipedia.org/wiki/Residual_sum_of_squares) of saturated model just like [`anova` in R](https://www.rdocumentation.org/packages/stats/versions/3.6.2/topics/anova), while in [`GLM.ftest`](https://juliastats.org/GLM.jl/stable/api/#GLM.ftest), the denominator is replaced by [RSS](https://en.wikipedia.org/wiki/Residual_sum_of_squares) of subsequant model.

This function works identically as [`StatsModels.lrtest`](https://juliastats.org/StatsModels.jl/stable/api/#StatsModels.lrtest).
!!! note
We can also specify test by keword arguments `test` or putting test in the first argument.
