dblexpv

double dblexpv(double p, double m, double s);

Returns the critical point of the Double Exponential random variable distribution function with mean m and scale parameter s associated with probability p.

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

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

Errors:
NUMERICS_ERROR is raised if s ≤ 0

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