Returns the cumulative distribution function, its inverse, or one of its parameters, of the gamma distribution. The kind of the return value and parameters (par1,par2, andpar3) are determined bywhich. The following table lists the return value and parameters bywhich. CDF, x, k, and theta...

The inverse cumulative function is already implemented for the Gaussian distribution, but not for the Gamma / Beta distributions. Although this may not be the best way to do so [1], this could be useful for using the "reparametrization trick" for Gamma / Beta distributions. ...

. To determine the predictive strength of each metric for each FS subtype, we calculated the detect probability (DP) (DP > 0.5 indicates higher values predict hits; DP < 0.5 misses; ideal observer analysis). The median, lower, and upper quartiles of each distribution are reported inTable ...
