The HPIMPUTE Procedure

IMPUTE Statement

IMPUTE variables <options> ;

The IMPUTE statement names the variables whose values PROC HPIMPUTE imputes. You can specify multiple IMPUTE statements. The IMPUTE statement takes only numeric variables; character variables are reported as an error. The variables in an IMPUTE statement must appear in an INPUT statement; if they do not appear in an INPUT statement, an error is reported.

You can specify the following options:

METHOD=MEAN | RANDOM | PMEDIAN

specifies the method of imputation. You can specify the following values:

MEAN: replaces missing values with the algebraic mean of the variable. If there is no nonmissing value, the mean is 0.
RANDOM: replaces missing values with a random value that is drawn between the minimum and maximum of the variable. If there is no nonmissing value, the random value is 0.
PMEDIAN: replaces missing values with the pseudo-median of the variable. If there is no nonmissing value, the pseudo-median is 0.

VALUE=value

replaces missing values with the specified value.
