PHat.test

Description

This function provides single-sided and two-sided tests of the probability of superiority (phat).

Usage

PHat.test(x, y, alpha = 0.05, alternative = "two.sided", sigfig = -1)

Arguments

x

The data from one group

y

The data from the alternative group

alpha

The significance level of tests which also controls the values of the confidence interval (default 0.05)

alternative

This defines whether a one-sided test or a two-sided (default) test is required. For a one-sided test use parameter values greater' or 'less' to define whether the d-value should be greater or less than zero.

sigfig

is the number of significant digits in the data.

Value

The values of phat and its standard error,the t-value, its pvalue and the upper and lower confidence interval.
