|
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. |
max.score |
The max possible response value in test data (the lowest response value should be 0). By default max.score=1 (i.e.,binary test data). max.score = 2 if the response categories are (0, 1, 2), etc. |
round.decimal |
The number of digits or decimal places for the imputed value. The default value is 0. |
