##General hypothesis : was that participants who had experienced more traumatic events
## during childhood would be more likely to drop out of treatment.
trau=matrix(c(25,13,9,10,6,31,21,6,2,3), byrow=TRUE, nrow=2)
colnames(trau)<-c("0","1","2","3","4+")
rownames(trau)<-c("dropout","remain")
ordinal.chisq(trau)
