Prediction testing


I am trying to test a model I have created for prediction. I keep trying to use the predict.interval command, but I continue getting an error message this this command is not found.

Error: object 'predict.interval' not found

If someone has any idea as to why I'm having this problem, I would love some help.


There isn't a function called predict.interval(). If you post a sample of your code, then we may be able to help better

Will this work?

predict(model, newdata, interval="confidence")
