In lubnaamro/MissPair: Tests for Matched Pairs Designs with Missing Values

A weighted permutation test for paired data with missing values in both arms

Description

The WPT function calculates the weighted studentized permutation test for testing H0m: mu1 = mu2 for matched pairs with missingness in both arm. WPT test is a combination of the randomization version of the paired t-test (Konietschke and Pauly, 2014) and Janssen's permutation version for the Welch test (Janssen, 1997) for complate and incomplete data respectively.

Usage

WPT(
  x,
  y,
  alternative = c("two.sided", "less", "greater"),
  nperm = 10000,
  alpha = 0.05
)

Arguments

x	a (non-empty) numeric vector of data values representing the first components of the pairs.
y	a (non-empty) numeric vector of data values representing the second components of the pairs.
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.
nperm	The number of permutations used for calculating the weighted permutation test. The default option is 10,000.
alpha	A number specifying the significance level; the default is 0.05.

Value

A WPT object containing the following components:

Input	The data input of the user.
Descriptive	Some descriptive statistics of the data. Displayed are the number of individuals per variable, the mean, and variance.
WPT	The value of the weighted test staistic and the p-value of the permutation procedure, as well as the test decision of the weighted permutation test.
