Abstract

This paper investigates a problem which arises when we wish to estimate a regression coefficient using a distance variable between a pre-determined point and a spatial data unit. First, we show that the variance of the regression coefficient decreases with the number of the units and propose a desirable number of the units whose variance is close to that of a disaggregated model. Second, we obtain the shapes of the units that achieve the minimum and the maximum variances assuming a constant number of the units to examine the influence of the shape of the units on the variance.
