Wherever I look up the following reference the name of the author is spelled Mauchly contrary to the naming of the R function. Mauchly, J.W., Significance test for sphericity of a normal $n$-variate distribution, Annals of mathematical statistics, 11(1940), p. 204-209. Is this a typo on the original article (which R Core has corrected) or is it a typo in the function name ? Best regards, Tobias

...s diff?rentes j'aimerai pouvoir faire une comparaison de k moyennes selon ces deux variables date et EU ANOVA ? n facteurs n'est pas la bonne solution je voudrai savoir qu'elles sont les tests qui permettent de r?soudre ce probl?me (?chantillons appari?s) je suis partis sur le test de Mauchley sans r?ussite pouvez vous m'aider merci S?bastien Hello, i would like to compare the k means of DW with two parameters (date and traitement) but i don't use ANOVA with n factors (aov) because i have a link between wk2 and wk1, wk3 and wk1-wk2 ... (matched samples). if you know the test...

Hello, I've assembled a Multivariate ctv (with a lot of help from Achim Zeleis, who has now posted the view on CRAN). I'd be grateful for comments regarding missing packages / functions. Opinions on the organisation of the view would also be appreciated, as well as having any errors pointed out. I've adopted a rather broad and vague definition of "multivariate", which may

...dom. Methods for (lm and) mlm. estVar(obj) obj$SSD/obj$df (could have methods for lm/mlm too) Convenience functions: Tr is the trace operator sum(diag(M)) proj is the projection operator possibly generalized to matrices. Rg: matrix rank (not sure we really need it, but see below) mauchley.test(obj, M=diag(ncol=p), T = proj(X, orth=TRUE), X = matrix(rep(1,p))) (p = ncol(obj$SSD)) Test of sphericity, i.e. that the obj represents a empirical covariance matrix S with true value proportional to M or that TST' is proportional to TMT'. Alternatively,...

...tion terms when the model and the upper scope had different orders for the main effects. (PR#7842) o A bug had sneaked into the anova.mlmlist() code, affecting the Greenhouse-Geisser epsilon. Code wrongly assumed a matrix to be symmetric. (Thanks to Bela Bauer.) o anova.mlmlist() and mauchley.test() are now more tolerant to rank deficiency in the M and X matrices (also when they are implicitly generated via model.matrix()). o anova.mlm had a scoping issue (PR#7898) o pf() with infinite df is allowed again. It is now more accurate for extreme ratios of dfs, especially whe...
