Dear ElMaestro, dear all

since I have the "privilege" to work sometimes with Kinetica, I obtained the new version 5.1 SP1 pack released by Thermo Fisher in 2014, where they fixed the statistical part for the unbalanced studies.

Compared to the previous version, they mention now at the end of analysis:
- ANOVA analysis: Point estimate and confidence interval derived from the least squares estimate (marginal means). - for a balanced study
and for incomplete block analysis: Point estimate and confidence interval derived from the arithmetic means.

Perhaps I am wrong, but calculation based by arithmetic means cannot give bias in such studies?

Wish you a happy weekend.

Ioana
