double logisticv(double x, double m, double b);
Returns the critical point of the Logistic random variable distribution function with mean m and beta b associated with probability p.
Parameters:
x | Cummulative probability for the critical point. |
---|---|
m | Mean parameter. |
b | Scale parameter. |
Returns:
x such that P(X ≤ x | m, b) = p
Errors:
NUMERICS_ERROR
is raised if b ≤ 0, p ≤ 0, or p ≥ 1
Usage:
double x = logisticv(.5, 1.5, 2.75)
