Dear All, I am running the mvProbit model to estimate five equation probit models. In my data all the dependent variables are dichotomous with values 0/1 and lables TRUE/FALSE. The explanatory variables are composed of catagorical and countinous variables. I specified the model as follows
Result<-mvProbit( cbind(y1,y2,y3,y4,y5) ~ x1+x2+x3+......+.x11,data=mydata) summary(Result) However, i get an error message "...Error in mvProbit(cbind(y1,y2,y3,y4,y5) ~:all dependent variables must be either 0,1,TRUE, or FALSE) I have checked all the dependent variables and it is coded 0/1 and lables TRUE/FALSE. Ofcourse there are two missing observation and I attempted to handle that with na.action=na.omit but even that didnt solve the problem. My second attempt was to tell r that the dichotomous dependent variables and the catagorical independent variables as factor as follows mydata$y1<-factor(mydata$y1) ... ... .. . mydata$x3<-factor(mydata$x3) But still problem not solved. How would I solve this problem? Thank you!
