I have a data set (in the form of a histogram) with a first peak that appears near zero. The second, lower peak appear later.
A lognormal pdf is not enough for this kind, I believe, since there are two peaks. I want to use the sum of two lognormal pdf's (different mu and sigma). Please help me how to demonstrate this. Thanks

You split your data into two sets.....and then apply the fit.
