N2 - The need for the use of computational intelligence techniques for missing data imputation has been overlooked in the literature. This is due to the complexity of computational intelligence techniques and as a result, researchers devote to easier and perhaps, inefficient techniques. In this paper, the theory and practice of using computational intelligence techniques for missing data imputation is explored. Commonly used techniques are reviewed and the latest computational intelligence techniques and their applications are presented. The paper also addresses the trade-offs between traditional heuristics and computational intelligence techniques. Research implications and major challenges in the subject area are discussed whereas new research directions are pointed by highlighting the key issues in the field.
