sexit_thresholds

Find Effect Size Thresholds

Description

This function attempts at automatically finding suitable default values for a "significant" (i.e., non-negligible) and "large" effect. This is to be used with care, and the chosen threshold should always be explicitly reported and justified. See the detail section in sexit() for more information.

Usage

sexit_thresholds(x, ...)

Arguments

`x`	Vector representing a posterior distribution. Can also be a `stanreg` or `brmsfit` model.
`...`	Currently not used.

Examples

sexit_thresholds(rnorm(1000))

    iter = 200,
    refresh = 0
  )
  sexit_thresholds(model)

  model <- stan_glm(vs ~ mpg, data = mtcars, family = "binomial", refresh = 0)
  sexit_thresholds(model)
}

if (require("brms")) {
  model <- brm(mpg ~ wt + cyl, data = mtcars)
  sexit_thresholds(model)
}

  bf <- ttestBF(x = rnorm(100, 1, 1))
