Any way to compute 2-way unbalanced ANOVA in Excel?

[MrNicolas]

Hi everyone!

I've been using the Excel Analysis Toolpak to perform 2-way ANOVAs. Problem is the feature does not allow for unbalanced data, which I often have.
Does anybody have any hint on how to solve the problem?

Cheers

Hi Mr. Nicolas
I know the trick. The free version of XLSTAT allows to run anova on unbalanced designs and to include 2 way interactions. If you do not know the tool, you can get it at http://www.xlstat.com
