Fisher matrix confidence bounds
WebApr 4, 2024 · As explained in the theoretical part of this vignette the Beta-Binomial confidence bounds should be applied to the output of rank_regression() whereas Fisher’s normal approximation confidence intervals are only applicable if the parameters and the variance-covariance matrix were estimated with ml_estimation().
