The HPIMPUTE Procedure

The HPIMPUTE procedure executes high-performance numeric variable imputation. Imputation is a common step in the data preparation stage. The HPIMPUTE procedure takes only numeric variables.

The HPIMPUTE procedure can replace numeric missing values with a specified value. It can also replace numeric missing values with the mean, the pseudo-median, or some random value between the minimum value and the maximum value of the nonmissing values.

When PROC HPIMPUTE calculates the mean, the pseudo-median, or a random value, it ignores any observation that has a FREQ variable whose value is less than or equal to 0.

The HPIMPUTE procedure runs in either single-machine mode or distributed mode.

Note: Distributed mode requires SAS High-Performance Server Distributed Mode .
