spatial association marginal contributions derived from spatial stratified heterogeneity

Usage

ssh_marginalcontri(formula, data, overlay = "and", cores = 1)

Arguments

formula: A formula of ISP model.
data: A data.frame, tibble or sf object of observation data.
overlay: (optional) Spatial overlay method. One of and, or, intersection. Default is and.
cores: (optional) Positive integer (default is 1). When cores are greater than 1, use multi-core parallel computing.

Value

A list.

pd: robust power of determinants
spd: shap power of determinants
determination: determination of the optimal interaction of variables

Examples

NTDs1 = sf::st_as_sf(gdverse::NTDs, coords = c('X','Y'))
g = ssh_marginalcontri(incidence ~ ., data = NTDs1, cores = 1)
