'Usage Dim instance As CalcGammaDistFunction Dim args() As Object Dim value As Object value = instance.Evaluate(args)
Parameters
- args
The args contains 4 items: x, alpha, beta, cumulative.
X is the value at which you want to evaluate the distribution.
Alpha is a parameter to the distribution.
Beta is a parameter to the distribution. If beta = 1, GAMMADIST returns the standard gamma distribution.
Cumulative is a logical value that determines the form of the function. If cumulative is TRUE, GAMMADIST returns the cumulative distribution function; if FALSE, it returns the probability density function.
