Straightforward application of OLS to statistical mass appraisal models does not always produce defensible estimates due to debilitating levels of multicollinearity in the data as appraisers attempt to improve the predictive ability of their models through the inclusion of a long list of...

This article provides a matrix representation of the adjustment grid estimator. From this representation, one can invoke the Gauss-Mrkov theorem to examine the efficiency of ordinary least squares (OLS) and the grid estimator that uses OLS estimates of the adjustments (the "plug-in" grid...

Many of the results from real estate empirical studies depend upon using a correct functional form for their validity. Unfortunately, common parametric statistical tools cannot easily control for the possibility of misspecification. Recently, semiparametric estimators such as generalized...
