Rpart modelling a decisión tree and getting probability
...the deseasse), but we only have the combination of predictive variables for a particular person.
We have created this code:
library( rpart)
fit1 <- rpart(sickness~ aetinghabit+gse+age+sex, method="class", data=data)
prediccion<-predict(fit1,bigdatabase, type="prob")
predictionsyes<-prediccion[,2]
pred <- prediction(predictionsyes, datos$sickness) # but this is
My question is. How do I put the people's conditions in this model in order to get the people probability of getting this desease? It's possible to do a ROC curve using only this bigdatabase? Because...
