This function imputes for all missing responses using predictive mean matching.
The mice () function with default settings from the mice package (Van Buuren & Groothuis-Oudshoorn, 2011
<doi: 10.18637/jss.v045.i03>) is used to impute for the missing responses.
Usage
micePMM(test.data, Mvalue = "NA")
Arguments
test.data
Test data set (a data frame or a matrix) containing missing responses.
Missing values are coded as NA or other values (e.g., 8, 9).
Mvalue
Missing response indicators in the data (e.g. "NA", "8", "9", etc.). Mvalue="NA" by default.
Value
A data frame with all missing responses replaced by integrated imputed values.
