An Estimation of Density Gradient Using Mesh Data

Abstract

Mesh data system is convenient for density gradient analysis as we can obtain many samples even in small cities. However, there is a difficult problem in specifying sample region since the value of density gradient estimater depends on the range of sample region. This paper proposes a way how to decide the range through statistical study of log linear estimaters. Gradient densities of 10 cities and 3 periods are estimated in this way.
