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 pseudomedian, or some random value between the minimum value and the maximum value of the nonmissing values.

When PROC HPIMPUTE calculates the mean, the pseudomedian, 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 .
