Hi there I 3 DV and IV( categorical :age, job, sex, studies, marital and continuous such hoursperday , days per week,children) I would like to check which of the IV effect the DV and analyse them. My data is coming form a questionnaire that I hand it out. I am little be confused of whick mathod I have to use but I decide that maybe I need MANOVA and create the model Y1<-cbind(score.sol, score.com.ext, score.pur) MANOVA.test<-manova(Y1~fsex+fjob+fage+fmarital+fstudies+hrperday+days+children) summary(MANOVA.test,test="Wilks") summary.aov(MANOVA.test) and after that if I want to compare two model MANOVA.test<-manova(Y1~fsex+fjob+fage+fmarital+fstudies+hrperday+days+children) MANOVA.test1<-manova(Y1~fsex+fjob+fage+fmarital+fstudies+hrperday) anova(MANOVA.test,MANOVA.test1 , test="Wilks") But is this correct?? or I should include only categorical variables and not continuous. Is the fuction of testing the models correct???
