static bone scan was performed in 46 patients for evaluation of ocular hydroxyapatite vascularization. study findings indicated that bone scan, with tc-99m mdp is an appropriate method for evaluation of hydroxyapatite vascularization and for estimating the time for peg insertion into the hydroxyapatite implant. our study showed proper hydroxyapatite vascularization when the ratio of activity in...

Multiple imputation has become viewed as a general solution to missing data problems in statistics. However, in order to lead to consistent asymptotically normal estimators, correct variance estimators and valid tests, the imputations must be proper. So far it seems that only Bayesian multiple imputation, i.e. using a Bayesian predictive distribution to generate the imputations, or approximatel...
