I have a problem with data fitting to gamma distribution. I have rainfall occurrences (calculated using 1st order 2 states Markov Chain analysis) for more than 30 yrs. I want to fit those data into Gamma Distribution and estimate parameters (Alpha and Beta). Then I want to simulate rainfall amounts.
Can anyone help me? The way how to do is enough.
I have Mathematica, SPSS, SAS, Excel, etc.
Thanks!
