# multi-factor model

1. ### What are the factors that best differentiate the two groups?

Hello Everyone, I am conducting a sports study. I have these data and I would like to answer this question: What are the factors that best differentiate the two groups? I have 2 groups of 17 professional athletes, 17 NBA and 17 MLB players with a total of 64 factors (kinetics and kinematics)...
2. ### Im terrible at this. Help Please!

Ok so I'm pretty sure this should be simple enough but Im not good at this at all. Basically; 32 participants tested (within design). They all completed 3 tests (subject test, URL test, email test) before training. Then they all completed 3 tests (subject test, URL test, email test) after...
3. ### Need Complex Ordinal Analysis

My question outlines the need for a non-parametric analysis of ratio data. I have a data set composed of apnea counts for individual mice during different breathing conditions and a drug. This boils down to a three factor ANOVA style data set Factor 1 -> Mouse Strain Factor 2 -> Gas...
4. ### 2^4 On-farm trial - only 4 plots per farm -> what design possibilities?

Hello, I have to design an on-farm trial with possibly about 600 farmers involved (setting: Madagascar, so rather illiterate participants). There are 4 factors, each at two levels (possibly one at 3 levels but that might get too complicated). Each farmer should have a maximum of four...
5. ### The multi-factor model is a multivariate gaussian distribution?

I'm sure that the following question is trivial, but I can't found a solid demonstration. Can we state that multi-factor model is a multivariate gaussian distribution? multi-factor model: X_ij = sigma_i * Z_i + sqrt(1-sigma_i^2)* E_ij where i=1,...,k j=1,...,n_i 0 < sigma_i <...
