Spatio-temporal Geographically Weighted Regression Analysis
Feature Description
Spatio-temporal Geographically Weighted Regression is an extended and improved version of Geographically Weighted Regression, capable of analyzing spatial coordinate points with temporal attributes, addressing spatiotemporal non-stationarity issues in models.
Application Scenarios
- Study urban housing variation trends across temporal and spatial dimensions
- Investigate provincial economic development factors and their spatiotemporal patterns
Parameter Description
| Parameter | Default Value | Description | Parameter Type |
|---|---|---|---|
| Source Dataset | Specified vector dataset for computation. Supports point, line, and polygon datasets | DatasetVector | |
| Explanatory Fields | Names of explanatory fields. Explanatory variables (independent variables X in regression equations) used for modeling/predicting dependent variables | String | |
| Kernel Function Type | GAUSSIAN | Type of kernel function | KernelFunction |
| Dependent Field | Dependent field. The variable under study/prediction (numerical fields only) | String | |
| Time Field | Field representing temporal attributes | String | |
| Time Unit | Days | Unit for temporal interval conversion. Supports: Seconds, Minutes, Hours, Days, Weeks, Months, Years. Example: 60 minutes converts to 1 Hour or 1/24 Day. Smaller units yield larger interval distances, affecting kernel function weights accordingly | TimeSpanUnits |
