Confirmatory adaptive designs with Bayesian decision tools for a targeted therapy in oncology.
29 Apr 2009 The ability to select a sensitive patient population may be crucial for the development of a targeted therapy. Identifying such a population with an acceptable level of confidence may lead to an inflation in development time and cost. We present an ...

The Wilcoxon-Mann-Whitney test under scrutiny.
29 Apr 2009 The Wilcoxon-Mann-Whitney (WMW) test is often used to compare the means or medians of two independent, possibly nonnormal distributions. For this problem, the true significance level of the large sample approximate version of the WMW test is known ...

Quantifying the source of infection for HIV-infected hemophiliacs in the U.K. from 1979 to 1984.
29 Apr 2009 There is considerable literature on the risk of HIV infection for individuals suffering from hemophilia A in the United Kingdom (U.K.) during the period 1979-1984 when the sources of Factor VIII clotting factor were contaminated with HIV. Toward the ...

29 Apr 2009 In a binary model relating a response variable Y to a risk factor X, account may need to take of an extraneous effect Z that is related to X, but not Y. This is known as the association pattern Y-X-Z. The extraneous variable Z is commonly included ...

Adaptive designs with correlated test statistics.
29 Apr 2009 In clinical trials, the collected observations such as clustered data or repeated measurements are often correlated. As a consequence, test statistics in a multistage design are correlated. Adaptive designs were originally developed for independent ...

Using multiple frames in health surveys.
29 Apr 2009 In this paper, we look at a unified approach to estimation in multiple frame surveys that enables the analysis to be handled with standard survey software. We investigate how the approach performs with data from the Auckland Diabetes, Heart and ...

29 Apr 2009 Researchers are often faced with the task of trying to measure abstract concepts. The most common approach is to use multiple indicators that reflect an underlying latent variable. However, this 'effect indicator' measurement model is not always ...
