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.weight
— Functionweight(object, method)
Weight spatial object
with method
.
GeoStatsBase.WeightingMethod
— TypeWeightingMethod
A method to weight spatial data.
GeoStatsBase.BlockWeighting
— TypeBlockWeighting(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.DensityRatioWeighting
— TypeDensityRatioWeighting(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 toLSIF()
)optlib
- Optimization library (default todefault_optlib(estimator)
)
Notes
Estimators from DensityRatioEstimation.jl are supported.
