Use this to predict the value for a future observation based on the current fitted linear regression model.

## Explanatory variate

Displays the name of the explanatory variate for which the values of the response variable are to be predicted from.

## Predict values at

Specify values of the explanatory variable to predict values of the response variable from. You can either type a single value, a series of values separated by columns or spaces, or the word **mean** to predict the mean value.

## Include variance of future observation

Specifies whether you want the variance of predictions to be calculated on the basis of forecasting new observations. The default is for the variance of predictions to be calculated on the basis of summarizing the data to which the data has been fitted.

## Display

Specifies which items of output are to be produced.
