Hi

I am not an expert in this area. Your error says

> 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)

str(mydata) tells you that you have factors.
$ tree           : Factor w/ 2 levels "FALSE","TRUE": 2 1 2 2 2 2 1 1 2 2 ...
$ nothing        : Factor w/ 2 levels "FALSE","TRUE": 1 1 1 1 1 1 1 2 1 1 ...
Maybe mvProbit is rather picky about input values.
So I would try to change those factors to its numeric representation by

mydata$tree <- as.numeric(mydata$tree)-1

You can use apply to change several factors to numeric at once.

Cheers
Petr

sorry for the confusion. I used y1,y2,.... instead of the real variable names just for emailing purpose (to forward my question in a more clear way). Tree, nothing...are the real variable names in my data set and i actually used
Result<-myProbit(cbind(tree,nothing....)~x1+x2......,data=mydata)

Hi

Keep your reply to rhelp list. Others can come with better/more appropriate solution.

Pardon me, but you used

Result<-mvProbit( cbind(y1,y2,y3,y4,y5) ~ x1+x2+x3+......+.x11,data=mydata)

but in mydata there are variables tree and nothing (according what you did tell us).

So I am rather confused.

Cheers
Petr

Thank you very much!
I find the following out put
1.  If I import the data with read.spss(....use.value.lables=FALSE) str(mydata) shows me:

$ tree           : atomic  1 0 1 1 1 1 0 0 1 1 ...
  ..- attr(*, "value.labels")= Named num  1 0
  .. ..- attr(*, "names")= chr  "TRUE" "FALSE"
$ nothing        : atomic  0 0 0 0 0 0 0 1 0 0 ...
  ..- attr(*, "value.labels")= Named num  1 0
  .. ..- attr(*, "names")= chr  "TRUE" "FALSE"
.
2.  If I import data with read.spss(....use.value.lables=TRUE) str(mydata)
shows me:


$ tree           : Factor w/ 2 levels "FALSE","TRUE": 2 1 2 2 2 2 1 1 2 2 ...
$ nothing        : Factor w/ 2 levels "FALSE","TRUE": 1 1 1 1 1 1 1 2 1 1 ...
regards

Hi

It shall work, I do not see any problem in the code. So you have to persuade us that you checked your data properly e.g. by posting result of

str(mydata)

Cheers
