Function to identify and generate the Missing at Random features (MAR)

Source: R/autoMAR.R

This function will automatically identify the missing patterns and flag the variables if they are not missing at random based on the AUC method

autoMAR(
  data,
  aucv = 0.9,
  strataname = NULL,
  stratasize = NULL,
  mar_method = "glm"
)

Arguments

data

[data.frame | Required] dataframe or data.table
aucv

[integer | Optional] auc cut-off value for the not missing at random variable selection
strataname

[text | Optional] vector of stratification variables
stratasize

[integer | Optional] vector of stratum sample sizes (in the order in which the strata are given in the input dataset).
mar_method

[text | Optional] missing at random classification method ("glm", "rf"). Default GLM is used (GLM runs faster for high dimensional data)

Value

list output including missing variable summary and number of MAR flag variables

Examples

# create missing at random features
marobj <- autoMAR (heart, aucv = 0.9, strataname = NULL, stratasize = NULL, mar_method = "glm")

#> less than or equal to one missing value coloumn found in the dataframe
