Jochen Wilhelm

You fitted fixed effects for 67 labs. That eats up all your degrees of freedom. You shouldconsider a mixed model fitting "labID" as a random effect.

Difo Voukang Harouna

Dear Prof. Jochen Wilhelm Thank you very much for your valuable support. I really appreciate. Please, how can I correct this degree of freedom? I mean could you please elaborate a bit on how I can fit the Lab ID as random effect!! I used XLSTAT!

Thank you very much Sir

Sorry, I don't use XLSTAT.
