signtest: The Sign Test

Description

A nonpametric test for center. The sign test compares the median to a value.

Usage

signtest(x, m = NULL, alpha = NULL,
alternative =c("two.sided", "greater", "less"), conf.level=NULL, exact = FALSE)

Arguments

x

A vector of sample data.

m

The median to test. Defaults to 0.

alpha

The Significance level, defaults to 0.05.

alternative

Defaults to two.sided. Used to determine what type of test to run.

conf.level

Defaults to NULL. Used to construct a confidence interval. Input as a decimal.

exact

Defaults to FALSE. Used to determine whether to run the exact procedure or a large sample approximation.

Value

B

The Test Statistic

Significance Level

Returns the alpha value.

P-value

Returns the p-value from the Sign Test.

Confidence Interval

The confidence interval requested.
