FIMIX PLS: group comparision on descriptive variables

Sir, I am struggling how to perform: A) weighting each descriptive info of each case by these probabilities and running this for all the classes and compare them. B) Assign each case to the class with highest probability and calculating the descriptives on the cases assigned to each latent. Please t...

Computing R2 in FIMIX-PLS

R² is the amount of explained variance, the variance represents the unexplained variance in FIMIX-PLS results. Thus, one minus the FIMIX-PLS variance should approximately provide you with the explained amount of variance.

Computing sample size of the above hierarchical model

I thank Professor Diogenes Bido for his valuable help. If we do power analysis for the above model - 1) A priory test (estimating sample size) using G*Power 3 Step 1: Go or click Tests => Correlation and regression => Linear multiple regression: Fixed model, R2 deviation from zero Step 2: From Type ...

Power analysis of Hierarchical model

Dear Sir, I am analyzing a (3rd order) Hierarchical model with PLS. Deails of the model is following: 1) A 3rd order construct which reflects 4 second-order constructs. A ==> B A ==> C A ==> D A ==> E(4) [construct E should be called second or first-order, I am not sure] 2) 3 second-order constructs...

Computing statistical power

How you calculated statistical power of whole PLS model? If you use G*Power, what we should select? Test family : t test? Statistical test : Linear multiple regression: Fixed model, single regression coefficient? Type of power analysis : Post hoc: Compute achieved power - given alpha, sample size, a...
