Combining Multiple Distributions into one Function

By Caryn | Mar 13, 2018 05:44AM CET

Hello!

I fitted a lognormal distribution to a year's worth of data. However, in order for it to make a larger impact, I need to fit multiple distributions to the data so I can see the differences. Is this possible in XLSTAT?

Hello Caryn,
It is not possible to fit multiple distributions at the same time. However, you could use the option Automatic in the general tab of the Distribution function dialog box in order to detect the best fitting distribution (determined using a Kolmogorov-Smirnov test).

Is there a way to fit multiple distributions in steps? Can I fit the distributions separately and then add them to one chart?
