spatial rough set-based ecological detector

Usage

srs_ecological_detector(y, x1, x2, wt, alpha = 0.95)

Arguments

y: Dependent variable, factor, character or discrete numeric.
x1: Covariate \(X_1\), factor, character or discrete numeric.
x2: Covariate \(X_2\), factor, character or discrete numeric.
wt: Spatial adjacency matrix.
alpha: (optional) Confidence level of the interval,default is 0.95.

Value

A list.

T-statistic: the result of T statistic for spatial rough set-based ecological detector
P-value: the result of P value for spatial rough set-based ecological detector
Ecological: does one spatial feature \(X_1\) play a more important role than \(X_2\)
