Has anyone had problems using fitdist before?

Hey everyone,

I am trying to use the fitdist function to model two separate distributions of data. I cannot directly compare the datasets because they are of different lengths. I was under the impression that fitdist was supposed to generate a probability plot, which would effectively normalize the data sets. The total area under the graphs of each fit should equal 1. However when I run the fitdist function on my data, it does not give me a probability plot. I have tried using this function on separate data in the past and got the correct plots. I'm not sure how to fix this. Any help is appreciated!

Hi Zvisco,

I understand that you want to use fitdist to fit two separate distributions of data and create a probability plot with normalized datasets.

You can look at the fitdist documentation page which has an example that shows plots for two different distributions. You mentioned that on executing fitdist, it does not give a probability plot. Can you tell us what you see when you use the fitdist function on your data? Could share the sample data and code so that the user community can help you better.
