Morphology

imputation = impute (semi-transparent) = impute + ion

Formally the noun is derived from 'impute', but the statistical/genetic meaning ('infer or assign missing data') is a specialized technical extension not obvious to general learners.

Etymology

The word imputation in genetics and statistics keeps the same idea from Latin imputare ('in' + 'to reckon'): it is like 'putting in' a guessed value by careful counting or thought. That's why researchers use imputation to fill in missing data or genetic details that were not directly seen.
