pageTest function

Page Rank Sum Test

Performs Page's ordered aligned rank sum test.

pageTest(y, ...)

## Default S3 method:
pageTest(
  y,
  groups,
  blocks,
  alternative = c("two.sided", "greater", "less"),
  ...
)

Arguments

• y: a numeric vector of data values, or a list of numeric data vectors.
• groups: a vector or factor object giving the group for the corresponding elements of "x". Ignored with a warning if "x" is a list.
• blocks: a vector or factor object giving the block for the corresponding elements of "x". Ignored with a warning if "x" is a list.
• alternative: the alternative hypothesis. Defaults to two.sided.
• ``: further arguments to be passed to or from methods.

Returns

A list with class "htest" containing the following components:

• method: a character string indicating what type of test was performed.
• data.name: a character string giving the name(s) of the data.
• statistic: the estimated quantile of the test statistic.
• p.value: the p-value for the test.
• parameter: the parameters of the test statistic, if any.
• alternative: a character string describing the alternative hypothesis.
• estimates: the estimates, if any.
• null.value: the estimate under the null hypothesis, if any.

Examples

## Sachs (1997), pp. 671 ff.
## 9 reviewers (blocks)
## assigned ranks to 4 objects (groups).
data(reviewers)
## See Sachs (1997) p. 677
