Comparison of Seventeen Missing Value Imputation Techniques

Abstract

Copious data are collected and put away each day. That information can be utilized to extricate curiously designs. However, the information that we collect is ordinarily inadequate. Presently, utilizing that information to extricate any data may allow deceiving comes about. Utilizing that, we pre-process the information to exterminate the variations from the norm. In case of a low rate of lost values, those occurrences can be overlooked, but, in the case of huge sums, overlooking them will not allow wanted results. Many lost spaces in a dataset could be a huge issue confronted by analysts because it can lead to numerous issues in quantitative investigations. So, performing any information mining procedures to extricate a little good data out of a dataset, a few pre-processings of information can be done to dodge such paradoxes and, in this manner, move forward the quality of information. For handling such lost values, numerous methods have been proposed since 1980. The best procedure is to disregard the records containing lost values. Another method is ascription, which includes supplanting those lost spaces with a few gauges by doing certain computations. This would increment the quality of information and would extemporize forecast comes about. This paper gives an audit on methods for handling lost information like median imputation (MDI), hot (cold) deck imputation, regression imputation, expectation maximization (EM), support vector machine imputation (SVMI), multivariate imputation by chained equation (MICE), SICE technique, reinforcement programming, nonparametric iterative imputation algorithms (NIIA), and multilayer perceptrons. This paper also explores some good options of methods to estimate missing values to be used by other researchers in this field of study. Also, it aims to help them to figure out what method is commonly used now. The overview may also provide insight into each method and its advantages and limitations to consider for future research in this field of study. It can be a baseline to answer the questions of which techniques have been used and which is the most popular.
