...problem. I also tried with a source code in R-2.1.1.tar but I think that there is some problem concerning the new version of gcc (4.x), so I downgraded it to gcc 3.4.5 but it does not work either.

...very useful for me the "qmvnorm" comand, but I see that it can compute only quantile for equicoordinate. Is it possible to have a curve (or a set of values) if we don't want equicoordinates?

...indi che i test da eseguire non dipendono dai risultati di test gi? eseguiti. Ho analizzato le query, ed ho notato che alla fine di ogni test esegue un rollback. Io ho installato nel mio sistema MySQL 4.1.20, ma questi rollback non funzionano. In pratica i test non funzionano, in quanto i primi metodi che esegue influenzano eccome i successivi. Qualcuno di voi ha gi? avuto esperienza di ci?, oppure pensate che i test automatizzati non siano parte integrante dello sviluppo (e non solo) di un progetto? grazie mille Ah dimenticavo, io le tabelle le ho create normalmente, come indicato dal li...

Hi all, I have the data from the posterior distribution for some parameter. I want to find the 95% credible interval. I think "t.test(data)" is only for the confidence interval. I did not fine function for the Bayesian credible interval. Could some one suggest me? Thanks [[alternative HTML version deleted]]

Dear Sir, I would like to ask whether there is any tool in R, developed for the function of non parametric Anova, where the non parametric analysis is able to compute the p-value for interaction as well (similar to Anova)? If not, would sir like to suggest any of the other statistical software around which would have this tool? Thank you. LYLing. ?SAVE PAPER! SAVE THE WORLD! - Please do not
