SciKit-GStat

Fit spatial dependence and produce ordinary-kriging estimates with their conditional variances. A fitted variogram is not itself evidence of predictive accuracy or calibrated uncertainty.

Inputs and conventions

Use coordinates shaped (n, 2) and one scalar observation per location. Record the coordinate reference system, distance units, measurement units and sampling support. For a regional Euclidean-distance model, project longitude/latitude into a suitable distance-based CRS before fitting. Resolve trends and repeated locations explicitly; do not silently perturb duplicate coordinates.
