Mean imputationAlessandro BarbieroGiancarlo ManziPier Alda Ferrari
Multiple imputation is a commonly used method for handling incomplete covariates as it can provide valid inference when data are missing at random. This depends on being able to correctly specify the parametric model used to impute missing values, which

In a previous work, it was clearly shown that the performance of the very simple imputation method based on Most Common Attribute Value called MC gave performance better than that of several complex imputation algorithms. And in that work [1] it was shown that the performance of MC was ...

One method is to include the inverse of the propensity score as a linear term in the imputation model [D. Firth and K.E. Bennett, Robust models in probability sampling, J. R. Statist. Soc. Ser. B. 60 (1998), pp. 321; D.O. Scharfstein, A. Rotnitzky, and J.M. Robins, ...
Missing values for smoking, CD4 count, viral load, and BMI were imputed using multiple imputation by chained equations which assumes data are missing at random. CD4 count, viral load and BMI were imputed as continuous variables and then categorized. All covariates were selected a priori based on...
(such as the median, minimum and maximum, range, or the IQR), thead-hocapproach is a study-level imputation. For instance, the sample median is often used as the estimate of the sample mean assuming symmetric distribution, and the sample standard deviation is commonly estimated by either\( ...
