factor detector

The factor detector q-statistic measures the spatial stratified heterogeneity of a variable Y, or the determinant power of a covariate X of Y.

Usage

factor_detector(y, x, confintv = FALSE, alpha = 0.95)

Arguments

y

Variable Y, continuous numeric vector.

x

Covariate X, factor, character or discrete numeric.

confintv

(optional) Whether to compute the confidence interval for the q statistic, default is FALSE.

alpha

(optional) Confidence level of the interval, default is 0.95.

Value

A list.

Q-statistic

the q statistic for factor detector

P-value

the p value for factor detector

CIL

the confidence interval lower bound

CIU

the confidence interval upper bound
