Prepare Hierarchical Duration Data — prepare_hierarchical_duration

Validates strictly positive finite uncensored durations, applies explicit unit conversion and recorded scaling, and runs the duration readiness gate.

Usage

prepare_hierarchical_duration_data(
  data,
  contract,
  condition_levels = NULL,
  condition_coding = c(-0.5, 0.5),
  scale_predictors = character(),
  scale_time = FALSE,
  outcome_multiplier = 1,
  converted_unit = NULL,
  missing = c("error", "drop")
)

Arguments

data: A data frame containing columns declared in contract.
contract: A duration gp3bayes_model_contract.
condition_levels: Optional two-value condition order.
condition_coding: Two distinct finite numeric condition codes.
scale_predictors: Declared numeric predictors to centre and scale.
scale_time: Whether to centre and scale the declared linear time variable.
outcome_multiplier: Positive unit-conversion multiplier.
converted_unit: Required destination unit when outcome_multiplier != 1.
missing: Either "error" or "drop".

Value

A gp3bayes_duration_prepared object.

Details

Zero, negative, non-finite, censored, truncated, or shifted durations are not supported. Unit conversion is never inferred.
