Jeffrey A. Lieberman,T. Scott Stroup,Joseph P. McEvoy,Joseph P. McEvoy,Marvin S. Swartz,Robert A. Rosenheck,Diana O. Perkins,Richard S.E. Keefe,Sonia M. Davis,C.E. Davis,Barry D. Lebowitz,Joanne B. Severe,John K. Hsiao +12 more
TL;DR: Olanzapine was the most effective in terms of the rates of discontinuation, and the efficacy of the conventional antipsychotic agent perphenazine appeared similar to that of quetiapine, risperidone, and ziprasidone.
Assessment of blinding in clinical trials
Heejung Bang,Liyun Ni,C.E. Davis +2 more
TL;DR: The blinding index proposed has the ability to detect a relatively low degree of blinding, response bias and different behaviors in two arms and is applied to a clinical trial of cholesterol-lowering medication in a group of elderly people.

A new distribution-free quantile estimator
Frank E. Harrell,C.E. Davis +1 more
TL;DR: In this article, a distribution-free estimator of the pth population quantile is formulated, where QP is a linear combination of order statistics admitting a jackknife variance estimator having excellent properties.

C.E. Davis,Sally Hunsberger,David M. Murray,Richard R. Fabsitz,John H. Himes,L. Stephenson,Benjamin Caballero,Betty J. Skipper +7 more
TL;DR: The design, rationale, and statistical procedures used in Pathways, a randomized, school-based intervention for the primary prevention of obesity in American Indian children, are reported.

C.E. Davis,Dana Quade +1 more
TL;DR: In this paper, the authors propose certain U-statistics as intuitively reasonable measures of skewness and as criteria for asymptotically distribution-free tests of symmetry.
