parameters (version 0.2.0)

parameters_bootstrap: Parameters bootstrapping

Description

Compute bootstrapped parameters and their related indices such as Confidence Intervals (CI) and p-values.

Usage

parameters_bootstrap(model, iterations = 1000, centrality = "median",
  ci = 0.95, ci_method = "quantile", test = "p-value", ...)

Arguments

model

Statistical model.

iterations

The number of draws to simulate/bootstrap.

centrality

The point-estimates (centrality indices) to compute. Character (vector) or list with one or more of these options: "median", "mean", "MAP" or "all".

ci

Value or vector of probability of the CI (between 0 and 1) to be estimated. Default to .89 (89%) for Bayesian models and .95 (95%) for frequentist models.

ci_method

The type of index used for Credible Interval. Can be "HDI" (default, see hdi) or "ETI" (see eti).

test

The indices of effect existence to compute. Character (vector) or list with one or more of these options: "p_direction" (or "pd"), "rope", "p_map", "equivalence_test" (or "equitest"), "bayesfactor" (or "bf") or "all" to compute all tests. For each "test", the corresponding bayestestR function is called (e.g. rope or p_direction) and its results included in the summary output.

...

Arguments passed to or from other methods.

Value

Bootstrapped parameters.
