...BT <- NULL COVALL <- 0 ### Q1: These are the permutations for the covariance matrix. Is this right? No repeats allowed because cov(X1, X1) equals variance? perm <- permutations(length(varList), 2, repeats.allowed = FALSE) ### Q2: A Bartletts test to check for hemogeneity of variance, which is prerequisite for gaussian error propagation. Does that make sense? if (type == "raw") { BT <- bartlett.test(varList) if (BT$p.value < 0.05) print("Bartlett's test indicates heteroscedasticity! Continuing anyway, but k...
