Dear listers,
I have the following problem. I would like to estimate the parameters of a
gammm(alpha,beta) distribution. I have however no data. Instead I have two
quantiles. Given values t1 and t2 and let x be gamma(alpha,beta), I have Pr
(x<t1)=0.1 and Pr(x<t2)=0.9. Would anyone be kind enough to suggest a method
for estimating these parameters.
Thanks in advance
Best wishes
Roger Gill
