Rejection probability for one sequence in the presence of selection bias
doublyF_value(R, bias, endp)data frame containing the non centrality parameters, the degrees of
freedom, the 1-alpha quantile corresponding to the central f distribution and
a numeric value for probability of false rejection of the null
hypothesis of no difference in the presence of selection bias.
