In SAP: Statistical Analysis and Programming

Hypothesis tests for two means

Description

Tests for means of two independent or paired groups.

Usage

TwoSamplesMeans(
  x,
  y,
  var.equal = FALSE,
  H1 = "two.sided",
  xvar = NULL,
  yvar = NULL,
  paired = FALSE
)

Arguments

x	a numeric vector for the data of the first group.
y	a numeric vector for the data of the second group.
var.equal	a logical variable indicating whether to treat the two variances as being equal
H1	a character string specifying the alternative hypothesis, must be one of "two.sided" (default),
xvar	a numeric value for the variance of the first group
yvar	a numeric value for the variance of the second group
paired	a logical indicating value whether you want

Details

TwoSamplesMeans function performs hypothesis tests on means of independent or paired two groups. Moreover, this function can decide whether it will use a parametric or non-parametric test.

Value

a list with 3 elements:

statistic	the value of the test statistic
df	If it is available, the degree of freedom for the test statistic
p.value	the p-value for the test
test	a character string indicating which method was used
