Coupling Coordination Degree (CCD)

Usage

ccd(data, weight = NULL, method = c("standard", "wang", "fan"), threads = 1)

Arguments

data

A numeric matrix or data.frame. Rows are observations, columns are indicators.

weight

Numeric vector of indicator weights. Must have length equal to ncol(data). If NULL, equal weights are used.

method

Coupling model. One of "standard", "wang", or "fan".

threads

Number of threads used in computation.

Value

A data.frame with:

  • C: coupling degree

  • D: coordination degree

Details

Note

Input values should be normalized to [0, 1].

Examples

set.seed(42)
mat = matrix(runif(20), nrow = 5)
