# Weighting

Geostatistical weighting is the process of assigning weights to geospatial data using the geospatial coordinates of the samples. Obtained weights are often used for declustering and importance sampling.

GeoStatsBase.BlockWeightingType
BlockWeighting(sides)
BlockWeighting(side₁, side₂, ...)

A weighting method that assigns weights to points in spatial object based on blocks of given sides. The number n of points inside a block determines the weights 1/n of these points.

GeoStatsBase.DensityRatioWeightingType
DensityRatioWeighting(tdata, [vars]; [options])

Density ratio weights based on empirical distribution of variables in target data tdata. Default to all variables.

Optional parameters

• estimator - Density ratio estimator (default to LSIF())
• optlib - Optimization library (default to default_optlib(estimator))

Notes

Estimators from DensityRatioEstimation.jl are supported.
