Table 2.

Standard errors (SE) from fitting the exponential model to predict risk of coronary heart disease to the full simulated data and SE and empirical SE found from fitting the exponential model to the complete records analysis after full simulated data sets were changed to missing, imputed data using baseline fully conditional specification (FCS) imputation and imputed data using the two-fold FCS algorithm.
