Hello everybody, Can anyone tell me how I could analyze data that are at a contigency table form? I already found function cfa in the cfa package but I still don't understand how I could use this function in order to elaborate a contigency table. Every answer is welcome! --------------------------------- ÁðïêôÞóôå ôçí äùñåÜí óáò@yahoo.gr [[alternative HTML version deleted]]

Every answer is welcome!I haven't looked at the cfa package, but the usual approach to analyze contingency tables would usually involve the functions: o table(), ftable(), xtabs() to generate contingency tables o chisq.test(), loglin(), loglm() to perform tests and fit loglinear models (the latter function is in the package MASS) See also the links on the respective help pages. hth, Z> > > --------------------------------- > > ????????? ??? ?????? ???@yahoo.gr > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help at stat.math.ethz.ch mailing list > https://www.stat.math.ethz.ch/mailman/listinfo/r-help

Test for independence with chisq.test(), but of course it is often more interesting to describe deviations from independence! There are correspondende analysis, for example corresp() from MASS, and sopme other packages to (look at ade4). There are multiple correspondence analysis, mca from MASS. There are liglinear models, use help.search("loglinear"). If some body knows what cfa does, please inform me to!!
