Improving efficiency and robustness of the doubly robust estimator for a population mean with incomplete data

Cao, Weihua; Tsiatis, Anastasios A.; Davidian, Marie - In: Biometrika 96 (2009) 3, pp. 723-734

Considerable recent interest has focused on doubly robust estimators for a population mean response in the presence of incomplete data, which involve models for both the propensity score and the regression of outcome on covariates. The usual doubly robust estimator may yield severely biased...

Likelihood and conditional likelihood inference for generalized additive mixed models for clustered data

Zhang, Daowen; Davidian, Marie - In: Journal of Multivariate Analysis 91 (2004) 1, pp. 90-106

Lin and Zhang (J. Roy. Statist. Soc. Ser. B 61 (1999) 381) proposed the generalized additive mixed model (GAMM) as a framework for analysis of correlated data, where normally distributed random effects are used to account for correlation in the data, and proposed to use double penalized...
