Hi guys. I am looking for a decent probability distribution to fit my data in. I have made some Q/Q-plots in SPSS. Especially the Gamma distribution does fit the data very well, and that does make sense. My data does have a large tail and has non-negative values only. However, I do not want to make my choice for a certain type of distribution on this Q/Q-plot only, since I think that this is not really 'scientific'
Are there any metrics that calculate the fit of a certain model with the data?
