As always, thank you very much, Rick for all your responses. They are helpful!

Thank you very much for your response. I need to clarify and ask you the following questions: 1) How could I put both the actual distribution and proc fmm generated mixture distributions on the same graph? 2) To clarify that even though there are some missing y values for x values from 4.2 to 8.0, the long right tail in general has an asymptote of 0.0003 with little volatility. How could I adjust the fmm procedure for that?

I have a couple of questions regarding the proc fmm output: 1) How could I convert histogram (the empirical data) into line graph? 2) The actual distribution graph looks like a gamma curve with alpha=3 and beta=0.5. x is from 0.01 to 8 by 0.01. Note that 1) there are lots of missing y values for x values starting from 4.2. 2) There's a lot of volatility in the counts which I need to capture in the fitted curve so that my cdf is actually approaching 1, not 0.92 or 1.2 Right now I am doing trial and error by changing the number of parameters, parameter starting values and distribution name. What is the best way to get the optimal fitted distribution result?

Thank you very much. I read your codes and understand how to get the cdf percentages.

Could anyone tell me how to specific an option in the proc fmm procedure to output the pdf and cdf percentages? I was able to run the proc fmm procedure to generate pdf fit statistics and pdf and cdf graphs, but I could not find an option to output the fitted pdf and cdf percentages. Thanks.

Thank you very much, Rick. You have identified the problem that the predworker is not a density, so it does not integrate to unity.

I thought I responded, but could not find my post. Rick, Thank you so much for your quick responses. Here are the parameters from the fitted gamma pdf procedure. I tried to attach the fitted graph in the quick reply, but I was not able to alpha=3.1264265313 beta=0.1878574508 lambda=0.0096286931

I appreciate your quick responses. Here are the parameters from the fitting procedure and I attached pdf graphs. Once again, thank you for your help. Alpha=3.1264265313 Beta=0.1878574508 Lambda=0.0096286931

I understand, but I did use lambda to get the final fitted gamma pdf. Lambda is a constant and we integrate pdf to get cdf , so if I simply multiply lambad by cdf("gamma", x, alpha, beta), I get very small number and it is no way near 1. What am I missing here?

I have fitted a distribution curve using gamma probability density distribution with 3 parameters. The following are my codes: proc nlin data=worker_distribution method=marquardt ; parameters alpha=3 beta=2 lambda=0.01 ; model percentcount=pdf("gamma",ratio,alpha,beta)*lambda; output out=fitworker predicted=predworker parms= alpha beta lambda; run; How do I create the cdf in SAS EG based on the fitted gamma pdf distribution? Thanks.
