[1] TRUE The main problem I have is that I need to evaluate the inverse of the normal Cumulative Distribution Function near 1 (but not exactly 1) and the PC cannot recognize it.
Evaluate it at 1, evaluate the density at 1, and use basic calculus to calculate the differential of the cumulative distribution for small differentials away from 1.
