When Is Extrapolation Appropriate?

Extrapolation is used in many scientific fields, like in chemistry and engineering where extrapolation is often necessary. For example, if you know the current voltages of a particular system, you can extrapolate that data to predict how the system might respond to higher voltages.

When can extrapolation be used?

"Extrapolation" beyond the "scope of the model" occurs when one uses an estimated regression equation to estimate a mean or to predict a new response y n e w for x values not in the range of the sample data used to determine the estimated regression equation.

Is extrapolation always appropriate?

Extrapolation is using the regression line to make predictions beyond the range of x-values in the data. Extrapolation is always appropriate to use. Extrapolation is using the regression line to make predictions beyond the range of x-values in the data. Extrapolation should not be used.
