Calculates IScores for multiple imputation functions

Usage

Iscores_compare(
  X,
  imputation_list,
  methods = NULL,
  N = 50,
  max_length = NULL,
  skip_if_needed = TRUE
)

Arguments

imputation_list: a list of imputation functions
methods: a character vector of names of methods in imputation_list. It can be NULL, then the function will attempt to get names from imputation_list object.

Value

a vector of IScores for provided methods

Examples

set.seed(111)
X <- matrix(rnorm(1000), nrow = 100)
X[runif(1000) < 0.4] <- NA

methods <- c("pmm", "cart", "sample", "norm.nob", "DRF")
imputation_list <- create_mice_imputations(methods)
