In the simple linear regression model confidence and predict

In the simple linear regression model, confidence and prediction intervals are utilized to provide interval estimates for an average and a particular value, respectively, of the dependent variable. The linear trend model in time series is an application of simple linear regression. This being said, discuss whether a confidence or a prediction interval is the relevant interval estimate for a linear trend model’s forecast.

Solution

sol)

No we can not use confidence or a prediction interval is the relevant interval estimate for a linear trend model’s forecast.We use moving average or exponential smoothing to forecast the model.
