APAStyler method for model tests from a vglm multinomial model

Description

APAStyler method for model tests from a vglm multinomial model

Usage

## S3 method for class 'modelTest.vglm'
APAStyler(
  object,
  format = list(FixedEffects = c("%s%s [%s, %s]"), EffectSizes =
    c("Chi-square (df=%s) = %s, %s")),
  digits = 2,
  pcontrol = list(digits = 3, stars = TRUE, includeP = FALSE, includeSign = FALSE,
    dropLeadingZero = TRUE),
  OR = TRUE,
  ...
)

Arguments

object

A modelTest.vglm class object, results from running modelTest() function on a class vglm object with a multinomial family

format

A list giving the formatting style to be used for the fixed effects and effect sizes.

digits

A numeric value indicating the number of digits to print. This is still in early implementation stages and currently does not change all parts of the output (which default to 2 decimals per APA style).

pcontrol

A list controlling how p values are formatted.

OR

a logical value whether to report odds ratios and 95 percent confidence intervals, if TRUE, or regression coefficients on the logit scale with standard errors, if FALSE.

...

Additional arguments.

Value

Styled results.

Examples

mtcars$cyl <- factor(mtcars$cyl)
m <- VGAM::vglm(cyl ~ qsec,
  family = VGAM::multinomial(), data = mtcars)
mt <- modelTest(m)

APAStyler(mt)

APAStyler(mt, OR = FALSE)
