Hi all
I've a continuous variable and I want to test (graphically, plotting
observed and theoretical distr, qqplot) whether it follows some formal
distribution. (some thing close to Ricci document : Fitting distributions
with R, Feb05).
The distribution I want to fit is a truncated Gamma at 1 (the minimal value
is 1), P(x)=Pgamma(rate,x)/(1-Pgamma(rate,x<1))
NB : changing the variable (x-1,ln(x)) didn't get satisfying results
