Void imputation rule set

Usage

imputation_rules_void

Format

An empty list.

Details

This imputation rule set includes the following minimal imputation steps:

Treatment administrations:

  • Expand administration episodes from the EX domain between EXSTDTC and EXENDTC.

  • Administrations inherit the administration time from EXSTDTC or EXENDTC.

  • The administration time is carried forward for subsequent administration events until the next imputed time.

Creating custom imputation rules

You can create your own imputation rule set by providing a named list with any combination of the four function slots: admin_pre_expansion, admin_post_expansion, obs_raw, and obs_final. Each function receives specific arguments depending on its slot.
