Generalized Likelihood Ratio Statistics and Uncertainty Adjustments in Efficient Adaptive Design of Clinical Trials
Hoeffding’s information bound Internal pilot Kullback-Leibler information Modified Haybittle-Peto test Multiparameter exponential family Sample size re-estimation
2011/6/20
A new approach to adaptive design of clinical trials is proposed in a general multi-
parameter exponential family setting, based on generalized likelihood ratio statistics and optimal
sequential tes...
Efficient adaptive designs with mid-course sample size adjustment in clinical trials
adaptive design conditional power futility Kullback-Leibler information sample size re-estimation
2011/6/17
Adaptive designs have been proposed for clinical trials in which the nuisance parameters
or alternative of interest are unknown or likely to be misspecified before the trial. Whereas most
previous w...
