show_var {mixgb}

Show multiply imputed values for a single variable

Description

Show m sets of imputed values for a specified variable.

Usage

show_var(imputation.list, var.name, original.data, true.values = NULL)

Arguments

imputation.list

A list of m imputed datasets returned by the mixgb imputer.

var.name

The name of a variable of interest.

original.data

The original data with missing data.

true.values

A vector of the true values (if known) of the missing values. In general, this is unknown (true.values = NULL).

Value

A data.table with m columns, each of which represents a set of imputed values for the variable of interest. If true.values is provided, an additional column will display the true values of the missing values.

Examples

# obtain m multiply datasets
params <- list(max_depth = 3, subsample = 1, nthread = 2)
mixgb.data <- mixgb(data = nhanes3, m = 3, xgb.params = params, nrounds = 20)

imputed.BMPHEAD <- show_var(
  imputation.list = mixgb.data, var.name = "BMPHEAD",
  original.data = nhanes3
)
imputed.BMPHEAD
