lognormalp

double lognormalp(double x, double m, double v);

Returns the value of the Lognormal random variable distribution function with mean m and scale parameter v at the value x.

Parameters:
xCritical point.
mMean parameter.
vVariance parameter.

Returns:
P(X ≤ x | m, v)

Errors:
NUMERICS_ERROR is raised if v ≤ 0

Usage:
double p = lognormalp(.5, 1.5, 2.75)
