WebFeb 15, 2024 · Fourth, the vignette says about the Cook's distance cutoff: The default is to use the 99% quantile of the F(p,m-p) distribution (with p the number of parameters including the intercept and m number of samples). A 99% quantile for a cutoff means that you can have 1% false positives. As the Cook's distance is calculated "for every gene and for ... WebUnited States. From ?results: "The default cutoff is the .99 quantile of the F (p, m-p) distribution, where p is the number of coefficients being fitted and m is the number of samples."
