Dear AFNI experts,

To further my understanding and reporting of a set of results I’ve been working with, I am checking one of the results from a 3dLME analysis using Excel. My design entails two within-subject factors (Session and Velocity) each with two levels, two quantitative variables of interest (Pleasantness and Oxytocin) and one quantitative covariate of no interest (Movement). Further, the quantitative variable Pleasantness is collected four times (once for each level of the two within-subjects factors) whereas Oxytocin and Movement are collected only two times (once at each level of the Session factor).

We see a main effect of Pleasantness in the following configuration:
-model “Session*Velocity*Pleasantness*Oxytocin+Movement”
-ranEff “1”
-SS_type 3

If the five terms in the model are, respectively, X1, X2, X3, X4, and X5, could you specify the regression equation that is being solved with the model I’ve used so that I can enter it into Excel?
