gauss.cor: Gauss Rank Correlation Estimator

Description

Compute the Gaussian rank correlation estimate

Usage

gauss.cor(x, y)

Arguments

x

a numeric vector; compulsory argument

y

a numeric vector; compulsory argument; x and y need to have the same length

Value

Upon successful completion, the function returns the Gaussian rank correlation estimate.

Details

gauss.cor computes the Gaussian rank correlation estimate for x and y.

Note that gauss.cor only works for x and y being numeric vectors, unlike the classical correlation measures implemented in cor which can also be computed for matrices or data frames.

Examples

# NOT RUN {
## create data
f <- function(x) ifelse(x > 0.9, x - 0.9, ifelse(x < -0.9, x + 0.9, 0))
x <- rnorm(25)
y <- f(x) + rnorm(25, sd=0.1)

## compute correlation
gauss.cor(x, y)
