expr_anova_nonparametric: Making text subtitle for nonparametric ANOVA.

Description

Making text subtitle for nonparametric ANOVA.

Usage

expr_anova_nonparametric(
  data,
  x,
  y,
  paired = FALSE,
  conf.type = "perc",
  conf.level = 0.95,
  k = 2,
  nboot = 100,
  stat.title = NULL,
  messages = TRUE,
  ...
)

Arguments

data

A dataframe (or a tibble) from which variables specified are to be taken. A matrix or tables will not be accepted.

x

The grouping variable from the dataframe data.

y

The response (a.k.a. outcome or dependent) variable from the dataframe data.

paired

Logical that decides whether the experimental design is repeated measures/within-subjects or between-subjects. The default is FALSE.

conf.type

A vector of character strings representing the type of intervals required. The value should be any subset of the values "norm", "basic", "perc", "bca". For more, see ?boot::boot.ci.

conf.level

Scalar between 0 and 1. If unspecified, the defaults return 95% lower and upper confidence intervals (0.95).

k

Number of digits after decimal point (should be an integer) (Default: k = 2).

nboot

Number of bootstrap samples for computing confidence interval for the effect size (Default: 100).

stat.title

A character describing the test being run, which will be added as a prefix in the subtitle. The default is NULL. An example of a stat.title argument will be something like "Student's t-test: ".

messages

Decides whether messages references, notes, and warnings are to be displayed (Default: TRUE).

...

Currently ignored.

Value

For more details, see- https://indrajeetpatil.github.io/statsExpressions/articles/stats_details.html

Details

For paired designs, the effect size is Kendall's coefficient of concordance (W), while for between-subjects designs, the effect size is epsilon-squared (for more, see ?rcompanion::epsilonSquared and ?rcompanion::kendallW).
