Multivariable-based correlation dimension analysis for generalized space
Yanguang Chen
Fractal geometry proved to be an effective mathematical tool for exploring real geographical space based on digital maps and remote sensing images. Whether the fractal theory tool…
Deriving two sets of bounds of Moran's index by conditional extremum method
Yanguang Chen
Moran's index is a basic measure of spatial autocorrelation, which has been applied to varied fields of both natural and social sciences. A good measure should have clear boundary…
Spatial autocorrelation equation based on Moran's index
Yanguang Chen
Based on standardized vector and globally normalized weight matrix, Moran's index of spatial autocorrelation analysis has been expressed as a formula of quadratic form. Further, ba…
Derivation of an Inverse Spatial Autoregressive Model for Estimating Moran's Index
Yanguang Chen
Spatial autocorrelation measures such as Moran's index can be expressed as a pair of equations based on a standardized size variable and a globally normalized weight matrix. One is…
Reconstruction and Normalization of Anselin's Local Indicators of Spatial Association (LISA)
Yanguang Chen
The local indicators of spatial association (LISA) are significant measures for spatial autocorrelation analysis. However, there is an inadvertent fault in Anselin's mathematical p…
Coefficient Decomposition of Spatial Regressive Models Based on Standardized Variables
Yanguang Chen
Spatial autocorrelation analysis is the basis for spatial autoregressive modeling. However, the relationships between spatial correlation coefficients and spatial regression models…
Exploring Spatial Patterns of Interurban Passenger Flows Using Dual Gravity Models
Zihan Wang, Yanguang Chen
Passenger flows in a traffic network reflect spatial interaction patterns in an urban systems. Gravity models can be employed to quantitatively describe and predict spatial flows.…
