Check Geometry – Bad Envelope
Geographic Information SystemsWhat makes a geometry invalid? Geometry that is considered invalid meets one of the following conditions: Empty—This condition occurs when the geometry of a feature has zero points and does not contain geometric information, represented by SHAPE_LEN and SHAPE_AREA fields, beyond its original initialization state. How do I fix invalid geometry in Arcgis? Start ArcMap.
Small sample size for geographically weighted regression; limitations
Geographic Information SystemsWhy do we use geographically weighted regression? GWR is useful as an exploratory technique – its usefulness as a prediction tool is controversial – it allows visualization of stimulus-response relationships and if/how that relationship varies in space. It also accounts for spatial autocorrelation of variables. Is geographically weighted regression machine learning? Machine Learning Methods Geographically-weighted
