A bi-objective k-nearest-neighbors-based imputation method for multilevel data

作者:

Highlights:

• A new imputation method for multilevel data was proposed.

• The method was described as a bi-objective optimization problem.

• The method was compared with benchmark imputation methods.

• Methods were tested on both simulated and benchmark data.

• The proposed method outperformed the traditional methods in most scenarios.
