Syntax. GAMMA.DIST(x,alpha,beta,cumulative)

Definition. This function returns the probabilities of a gamma-distributed random variable. Use this function to examine variables that have a skewed distribution. The gamma distribution is commonly used in queuing analyses.


  • x (required). The value (quantile) for which you want to calculate the probability (1-alpha).

  • alpha (required). A parameter of the distribution.

  • beta (required). A parameter of the distribution. If beta = 1, GAMMA.DIST() returns the standard gamma distribution.

  • cumulative (required). The logical value that represents the type of the function. If cumulative is TRUE, GAMMA.DIST() returns the value of the distribution function that is the probability that ...
