[R] Fitting Gamma distribution

2010-06-23 Thread Marcosco01
I'm looking for goodness of fit tests for gamma distributions with large data sizes and for different data. I have a matrix with around 4.000 data values about losses and there is a heavy right-tail in it. I have fitted a gamma distribution with "fitdistr". You can see the example: fitdistr

I'm looking for goodness of fit tests for gamma distributions with large data sizes. I have a matrix with around 10,000 data values in it and i have fitted a gamma distribution over a histogram of the data. The problem is testing how well that distribution fits. Chi-squared seems to be used more
