So we can parameterize the gamma function and with a calculus program like ‘Matlab’ or ‘ Excel’ we can evaluate the probability density function as indicated in figure 1 or figure 2 (note that k shall ...

See the "Response Probability Distributions" section for the definition of the gamma probability density function. A value of 1 for the index parameter corresponds to the exponential distribution .

The gamma probability distribution, with a shape parameter that varies linearly with number of days in a wet period and a scale parameter independent of length of a wet period, is shown to provide an ...

Similar formulae for the corresponding probability distribution functions are derived. The applicability of these results to the cases of the negative exponential, Weibull and gamma distributions is ...
