Hi Zeda, The short answer to your question is no. All you have are the parameter estimates with no information on variability which you would need to create a prediction interval. Given the great ease of fitting models in R, I would offer to refit the model for my boss, and then (with the model

I was given a list of parameter estimates from my boss. She wants to predict the dependent variable "fsshen" beyond jan 2011, the last observation, through December 2011, giving the prediction intervals (90%). I don't know if I have the complete information to do this. So my question(s) is can
