mice (version 2.7)

complete: Creates a Complete Flat File from a Multiply Imputed Data Set

Description

Takes an object of class mids, fills in the missing data, and returns the completed data in a specified format.

Usage

complete(x, action=1, include=FALSE)

Arguments

x

An object of class mids as created by the function mice().

action

If action is a scalar between 1 and x$m, the function returns the data with imputation number action filled in. Thus, action=1 returns the first completed data set, action=2 returns the se

include

Flag to indicate whether the orginal data with the missing values should be included. This requires that action is specified as "long", "broad" or "repeated".

Value

Details

The argument action can also be a string, which is partially matched as follows: [object Object],[object Object],[object Object]

Examples

# do default multiple imputation on a numeric matrix
imp <- mice(nhanes)          

# obtain first imputated matrix
mat <- complete(imp)         

# fill in the third imputation
mat <- complete(imp, 3)      

# long matrix with stacked complete data
mat <- complete(imp, "long") 

# long matrix with stacked complete data, including the original data
mat <- complete(imp, "long", inc=TRUE)

# repeated matrix with complete data
mat <- complete(imp, "r")    

# for numeric data, produces a blocked correlation matrix, where
# each block contains of the same variable pair over different
# multiple imputations.
