Evaluation of a weighting approach for performing sensitivity analysis after multiple imputation

Table 2 Estimates of the marginal mean of the normally distributed outcome variable under four analysis methods (n = 100, δ = 1); True value = 0

	Number of imputations (m)
	5	10	50	100	500	1000
Full dataset (before deletion)	−0.003
Complete Case Analysis	0.489
Multiple Imputation under MAR	0.323	0.322	0.322	0.322	0.322	0.322
Sensitivity Analysis under MNAR	0.196	0.155	0.078	0.046	−0.018	−0.044

Note: The empirical Monte Carlo standard errors were all around 0.003 for MI and 0.004 for sensitivity analysis
