Inverse prediction

I am looking for a way to do what I used to do with the DRC-package in R. Especially the prediction of x given y (inverse prediction e.g. in probit dose-response models). In R I used the functin ED() for this. Is there any function in Julia to do this? Rearranging the regression model of y on x is no option as I need correct confidence limits for the prediction. Something like “inverse.predict(glmmodel,newdata=50)”?
