How do you handle missing data in regression analysis?

Techniques for Handling the Missing Data

1. Listwise or case deletion.
2. Pairwise deletion.
3. Mean substitution.
4. Regression imputation.
5. Last observation carried forward.
6. Maximum likelihood.
7. Expectation-Maximization.
8. Multiple imputation.

What is Listwise deletion method?

In statistics, listwise deletion is a method for handling missing data. In this method, an entire record is excluded from analysis if any single value is missing.

How much is too much missing data?

Statistical guidance articles have stated that bias is likely in analyses with more than 10% missingness and that if more than 40% data are missing in important variables then results should only be considered as hypothesis generating [18], [19].

What happens if missing data in a logistic regression?

So if a case is missing data for any of the variables in the analysis it will be dropped entirely from the model.

How is Monte Carlo used in logistic regression?

A Monte Carlo simulation is applied to simulate data and then logistic regression parameters are estimated. Our findings show that, among the five missing data handling methods, multiple imputation performs well on both MCAR and MAR.

Which is the best method for missing data?

Abstract—The aim of this article is to compare five popular missing data handling methods: listwise deletion, mean substitution, regression imputation, stochastic imputation, and multiple imputation.

How to assign missing values to missing data?

A missing value of some i th feature/dimension f i ∈ X is lack of observation/knowledge about what particular value x ∈ X does it have. One can imagine a situation where we are asking people to fill out a multi-page survey, and after getting all the data it turns out we do not have one of the person’s pages.
