I wanted to fit my Data to the lognormal distribution, but I get this error message : "The data in X must be positive".

I am pretty sure that the data and the frequency arrays are positive (>=0).

How can I ovecome this issue.

Yes, I found some zeros.

I have to remove these values to be able to fitt my data to the Lognormal distribution.

Thank you for your help

I predefined the bin edges. for some bins the count is 0. Thus, the error.

0 is not positive. What does this command show?

any(Data(1, :) == 0)
