I would like to study how one variable depends on others. i tried with techniques liko glm and with this code: mod=lm(Variable ~.,data=...) step(mod) but i have some problems when i try with no-numerical variables. in particular i have this table <http://r.789695.n4.nabble.com/file/n4686150/prova.png> and i'd like to see how and how much (for example) "Stato riga" depends on other parameters. i hope I have been clear... Thank youuu!! -- View this message in context: http://r.789695.n4.nabble.com/dependence-of-a-variable-from-the-others-tp4686150.html Sent from the R help mailing list archive at Nabble.com.
