The probability inverse transform is defined generally as \hat{F}(y|x), which is the fitted conditional cdf of each observation evaluated at the observed response value. In the case of gldrm, the fitted cdf is descrete, so we draw a random value from a uniform distribution on the interval (\hat{F}(y|x), \hat{F}(y-|x)), where y- is the next largest observed support less than y (or -Infinity if y is the minimum support value). The output and plots generated by this function will vary slightly each time it is called (unless the random number generator seed is set beforehand).
Randomized robability inverse transform as a vector. Also plots the histogram and uniform QQ plot.
