locally explained stratified heterogeneity(LESH) model

Description

Function for locally explained stratified heterogeneity model.

Usage

lesh(formula, data, cores = 1, ...)

Arguments

formula

A formula of LESH model.

data

A data.frame, tibble or sf object of observation data.

cores

(optional) Positive integer (default is 1). When cores are greater than 1, use multi-core parallel computing.

...

(optional) Other arguments passed to rpart_disc().

Value

A list.

interaction

the interaction result of LESH model

spd_lesh

a tibble of the shap power of determinants

Note

The LESH model requires at least 2^n-1 calculations when has n explanatory variables. When there are more than 10 explanatory variables, carefully consider the computational burden of this model. When there are a large number of explanatory variables, the data dimensionality reduction method can be used to ensure the trade-off between analysis results and calculation speed.
