Check Duration Posterior Predictive Behaviour

Compares observed positive-duration summaries with replicated outcomes from the fitted posterior predictive distribution.

Usage

check_duration_posterior_predictive(
  fit,
  draws = 500L,
  seed = 1L,
  pass_probability = 0.8,
  review_probability = 0.95
)

Arguments

fit

A gp3bayes_duration_fit.

draws

Number of posterior predictive data sets.

seed

Non-negative integer seed.

pass_probability

Central predictive interval used for pass.

review_probability

Wider predictive interval used for review.

Value

A gp3bayes_duration_posterior_predictive_check.

Details

The check covers median, mean, upper-tail, dispersion, condition-ratio, and grouping summaries. It does not prove global model adequacy.
