bf_oneway_anova: Bayesian one-way analysis of variance.

Description

Bayesian one-way analysis of variance.

Usage

bf_oneway_anova(
  data,
  x,
  y,
  bf.prior = 0.707,
  caption = NULL,
  output = "null",
  paired = FALSE,
  k = 2,
  ...
)

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.

bf.prior

A numeric value between 0.5 and 2 (default 0.707), the prior width to use in calculating Bayes Factors.

caption

Text to display as caption (will be displayed on top of the Bayes Factor caption/message).

output

Can either be "null" (or "caption" or "H0" or "h0"), which will return expression with evidence in favor of the null hypothesis, or "alternative" (or "title" or "H1" or "h1"), which will return expression with evidence in favor of the alternative hypothesis, or "results", which will return a dataframe with results all the details).

paired

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

k

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

...

# NOT RUN {
# between-subjects -------------------------------------------------------

# to get caption (default)

  paired = FALSE
)

# to get results dataframe
bf_oneway_anova(
  data = iris,

  output = "results"
)
