winsor.cor.test: Winsorized correlation test (for paired data)

Description

Test for association between paired samples, using winsorized correlation coefficient.

Usage

winsor.cor.test(x, ...)
# S3 method for default
winsor.cor.test(x, y, tr=0.2,alternative = c("two.sided", "less", "greater"), ...)

# S3 method for paired
winsor.cor.test(x,tr=0.2,alternative = c("two.sided", "less", "greater"), ...)

Arguments

x

an object of class paired or the first variable.

y

second variable.

tr

percentage of winsorizing.

alternative

a character string specifying the alternative hypothesis, must be one of "two.sided" (default), "greater" or "less". You can specify just the initial letter.

…

further arguments to be passed to or from methods.

Value

A list with class "htest" containing the following components:

statistic

the value of the t-statistic.

parameter

the degrees of freedom for the t-statistic.

p.value

the p-value for the test.

estimate

the winsorized correlation.

null.value

the specified hypothesized value of the winsorized correlation (=0).

alternative

a character string describing the alternative hypothesis.

data.name

a character string giving the name(s) of the data.
