Error message examples

First parameter, «X», to GammaI, cannot be negative.

Cause

Function GammaI defines an incomplete gamma function. It returns the cumulative area under the Gamma distribution defined by «A» as the shape parameter and «B» as the optional scale parameter from 0 to «X». So, «X» must have a positive value.

Remedies

Correct the first parameter to the GammaI function to be a non-negative.
