double dblexpp(double x, double m, double s);
Returns the value of the Double Exponential random variable distribution function with mean m and scale parameter s at the value x.
Parameters:
x | Critical point. |
---|---|
m | Mean parameter. |
s | Scale parameter. |
Returns:
P(X ≤ x | m, s)
Errors:
NUMERICS_ERROR
is raised if s ≤ 0
