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...
Likelihood ratio type two-sample tests for current status data
Nonparametric two sample tests current status data likelihood ratio Weibull distribu-tions
2011/3/24
We introduce fully nonparametric two sample tests for testing the null hypothesis that the two samples come from the same distribution if the values are only indirectly given via current status censor...

Algebraic statistics factor analysis large sample asymptotics semi-algebraic set tangent cone
2010/4/27
Many statistical hypotheses can be formulated in terms of polynomial
equalities and inequalities in the unknown parameters and
thus correspond to semi-algebraic subsets of the parameter space.
We c...

We compute the loss of power in likelihood ratio tests when we test
the original parameter of a probability density extended by the first
Lehmann alternative.
