The distribution platform estimates lambda and sigma parameters for a Gamma-Poisson distribution of the attached data to be 10.0 and 4.4. A separate least-squares method finds 7.5 and 2.1. I am not proposing the orange line to be better than the gray (JMP) only that it fits my current needs better. For other data sets the parameters found by both systems are fairly close.
Does anyone have an idea as to what is happening here?
