lognormalv

double lognormalv(double p, double m, double v);

Returns the critical point of the Lognormal random variable distribution function with mean m and scale parameter v associated with probability p.

Parameters:
pCummulative probability for the critical point.
mMean parameter.
vVariance parameter.

Returns:
x such that P(X ≤ x | m, v) = p

Errors:
NUMERICS_ERROR is raised if v ≤ 0, p ≤ 0, or p ≥

Usage:
double x = lognormalv(.5, 1.5, 2.75)
