The Estimation and Interpretation of Urban Density Gradients
城市人口密度梯度的估计与解释
The negative-exponential varying-parameter, density-gradient model is generalized by introducing the Box–Cox transformation in conjunction with truncated and heteroscedastic errors. An interpretation of this density-gradient model is presented, based directly on the magnitude and response of the expected value of population density to changes in the model's conditioning variables. Previous studies interpreted the gradient parameters purely as descriptive statistics of…
