impute_internal {rbmi}

Create imputed datasets

Description

This is the work horse function that implements most of the functionality of impute. See the user level function impute() for further details.

Usage

impute_internal(
  draws,
  references = NULL,
  update_strategy,
  strategies,
  condmean
)

Arguments

draws

A draws object created by draws().

references

A named vector. Identifies the references to be used for reference-based imputation methods. Should be of the form c("Group1" = "Reference1", "Group2" = "Reference2"). If NULL (default), the references are assumed to be of the form c("Group1" = "Group1", "Group2" = "Group2"). This argument cannot be NULL if an imputation strategy (as defined by data_ice[[vars$strategy]] in the call to draws) other than MAR is set.

update_strategy

An optional data.frame. Updates the imputation method that was originally set via the data_ice option in draws(). See the details section for more information.

strategies

A named list of functions. Defines the imputation functions to be used. The names of the list should mirror the values specified in strategy column of data_ice. Default = getStrategies(). See getStrategies() for more details.

condmean

logical. If TRUE will impute using the conditional mean values, if values will impute by taking a random draw from the multivariate normal distribution.
