Gamma Distribution Calculator

With k = 1 the gamma reduces to the exponential; larger k makes it more symmetric and bell-like.

For whole-number k it models the total wait for k events of a Poisson process.

Stretches the distribution: the mean is kθ and the variance kθ². A larger θ means longer typical waits.

The value (e.g. a total waiting time) to evaluate. The tool reports the probability of falling below or above x.

A cumulative probability between 0 and 1; the tool returns the value x with a share p of the distribution below it.
