In nonpar: A Collection of Nonparametric Hypothesis Tests

Description

The 2 sample median test is for testing the medians of 2 samples to see if they are equal.

Usage

  mediantest(x, y, alpha=NULL, exact=FALSE)

Arguments

x	A vector containing data from the first sample.
y	A vector containing data from the second sample.
alpha	The Significance level, defaults to 0.05.
exact	Defaults to FALSE. Runs the exact test or a large sample approximation.

Value

Z	The test statistic for the large sample approximation.
P-value	Returns the p-value from the Median Test.

Examples

  ## Run the Median Test on the 2 vectors.
  mediantest(x = c(5.5, 5.8, 6.8, 6.9, 7.2, 7.3, 7.5, 7.6, 8.0),
             y = c(5.3, 5.4, 5.6, 5.7, 6.2, 6.4, 6.6, 6.7, 8.2), exact=TRUE)
