It is not always necessary to exclude a case with missing data. The decision to exclude or impute missing data depends on the amount and pattern of missing data, and the assumptions made about the missingness mechanism. There are various ways to handle missing data such as pairwise deletion, mean imputation, and multiple imputation. It is important to carefully consider the implications of each method and their potential biases on the analysis results.
