模型能力表¶
| 模型 | 类型 | 输入 | 新位置能力 |
|---|---|---|---|
GWR |
Classic local regression | X, y, coordinates | Validated local re-calibration at new coordinates. |
MGWR |
Multiscale local regression | X, y, coordinates | Independent-target prediction is intentionally unavailable in the current validated API. |
RGWR |
Robust local regression | X, y, coordinates | Validated local prediction using the fitted robust calibration state. |
STWR |
Stage-based spatiotemporal regression | Lists of X, y, and coordinates by stage, plus time intervals | Prediction for the current/latest stage using the fitted historical-stage weighting structure. |
GTWR |
Row-wise spatiotemporal regression | X, y, coordinates, and row-wise times | Validated at new space-time targets; causal filtering is available when configured. |
GWGLM |
Generalized local regression | X, response, coordinates; optional exposure for Poisson | Validated for Gaussian means, binomial probabilities, and Poisson means. |
GWLasso |
Locally regularized regression | X, y, coordinates | Validated local prediction with the learned local penalties and scaling state. |
MixedGWR |
Semiparametric global-local regression | X, y, coordinates, and global/local variable assignments | Validated using global coefficients and re-estimated local components. |
GWPCA |
Local multivariate transformation | Multivariate X and coordinates | Not a response predictor; transform() returns local component scores. |
GWDA |
Local spatial classification | X, class labels, coordinates | Validated class labels and local class probabilities. |
GWSS |
Local descriptive statistics | Multivariate X and coordinates | Not applicable; this is a local-statistics estimator. |
ScalableGWR |
Approximate scalable local regression | X, y, coordinates | Validated using the fitted scalable kernel approximation. |
LCRGWR |
Collinearity-compensated local regression | X, y, coordinates | Validated local prediction with fitted or locally adjusted ridge terms. |
BootstrapGWR |
Spatial inference | X, y, coordinates | Not applicable; the estimator performs coefficient-variability inference. |
SGWR |
Geography-plus-similarity regression | X, y, coordinates, and similarity-variable specification | Validated by recomputing geographic and attribute-similarity weights for targets. |
SGTWR |
Geography-time-similarity regression | X, y, coordinates, times, and similarity variables | Validated at target space-time points with optional causal filtering. |
MGTWR |
Multiscale spatiotemporal regression | X, y, coordinates, times; optional per-column bandwidths and taus | 当前已验证 API 不提供独立目标位置预测;模型拟合与推断由 pyGWRx 内部实现。 |
LGGWR |
Original research model | X, y, coordinates, and contextual attributes | Validated using the learned geometry transform and target attributes. |
GRGWR |
Original research model | X, y, coordinates, regime count, and connectivity settings | Validated using learned regime structure and target assignment logic. |
使用原则¶
- 先建立全局模型和标准 GWR 基线,再使用更复杂模型。
- 固定带宽是距离,自适应带宽是近邻数,不能直接比较数值大小。
- 局部系数不是自动的因果效应,必须结合不确定性、共线性和残差诊断。
- 时空模型必须使用防止未来信息泄漏的验证方式。
- LGGWR 和 GRGWR 是原创研究模型,应报告初始化、敏感性和当前验证边界。
