extrapolative expectations

extrapolative expectations

DEPENDENT VARIABLE from a value of the INDEPENDENT VARIABLE that is beyond the range of observed independent variables and outside the range; the trend line may be inaccurate because the underlying relationship may be different over the broader range. By contrast, if we interpolate, i.e. predict a value for the dependent variable from a value of the independent variable that lies within the range of observed independent variables, then the prediction is likely to be more reliable.
