Fig. 2From: Examining the vintage effect in hedonic pricing using spatially varying coefficients models: a case study of single-family houses in the Canton of ZurichCovariance functions. Two exponential covariance functions which are depending on a distance d and parametrized as given in Table 1. One can clearly see that the variance in Parametrization 1 is lower than in Parametrization 2. On the other hand, Parametrization 1 has a greater range which leads to slower decay of the covariance function over distanceBack to article page
