srsgd: spatial rough set-based geographical detector(SRSGD) model

Description

Function for spatial rough set-based geographical detector model.

Usage

srsgd(formula, data, wt = NULL, type = "factor", alpha = 0.95)

Value

A list.

factor

the result of spatial rough set-based factor detector

interaction

the result of spatial rough set-based interaction detector

ecological

the result of spatial rough set-based ecological detector

Arguments

formula

A formula of spatial rough set-based geographical detector model.

data

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

wt

Spatial adjacency matrix. If data is a sf polygon object, the queen adjacency matrix is used when no wt object is provided. In other cases, you must provide a wt object.

type

(optional) The type of geographical detector, which must be one of factor(default), interaction and ecological.

alpha

(optional) Specifies the size of the alpha (confidence level). Default is 0.95.
