geographically optimal zones-based heterogeneity detector

Function for geographically optimal zones-based heterogeneity detector.

Usage

gozh_detector(formula, data, cores = 1, type = "factor", alpha = 0.95, ...)

Arguments

formula: A formula of GOZH detector.
data: A data.frame or tibble of observation data.
cores: (optional) A positive integer(default is 1). If cores > 1, a 'parallel' package cluster with that many cores is created and used. You can also supply a cluster object.
type: (optional) The type of geographical detector,which must be one of factor(default), interaction, risk, ecological.
alpha: (optional) Confidence level of the interval,default is 0.95.
...: (optional) Other arguments passed to rpart_disc().

Value

A list of tibble with the corresponding result under different detector types.

factor: the result of factor detector
interaction: the result of interaction detector
risk: the result of risk detector
ecological: the result of ecological detector

Note

Only one type of detector is supported in a gozh_detector() run at a time.
