The bioequivalence problem is of practical importance because the approval of most generic drugs in the United States and the European Community (EC) requires the establishment of bioequivalence between the name brand drug and the proposed generic version. The problem is theoretically interesting because it has been recognized as one for which the desired… (More)
This article develops and implements a simulation approach to value patents and patent-protected R&D projects based on the Real Options approach. It takes into account uncertainty in the cost-to-completion of the project, uncertainty in the cash flows to be generated from the project, and the possibility of catastrophic events that could put an end to the… (More)
Not all simultaneous inferences need multiplicity adjustment. If the sequence of individual inferences is predeened, and failure to achieve the desired inference at any step renders subsequent inferences unnecessary, then multiplicity adjustment is not needed. This can be justiied using the closed testing principle to test appropriate hypotheses which are… (More)
Multiple comparisons with the best, which is applicable to single-stage experiments, is introduced as a method for choosing the best of a finite number of system designs. Examples are given.
Normalization of expression levels applied to microarray data can help in reducing measurement error. Different methods, including cyclic loess, quantile normalization and median or mean normalization, have been utilized to normalize microarray data. Although there is considerable literature regarding normalization techniques for mRNA microarray data, there… (More)
Some new quantile estimators that employ a control variate are introduced. The properties of these estimators do not depend on the usual assumption of joint normality between the random variable of interest and the control. Empirical results are presented.
This paper presents two simple algorithms to calculate the portfolio weights for a risk parity strategy, where asset class covariance information is appropriately taken into consideration to achieve " true " equal risk contribution. Previous implementations of risk parity either (1) used a naïve 1/vol solution, which ignores asset class correlations, or (2)… (More)
The CSAT Methamphetamine Treatment Project (MTP) is a multisite study with a two-fold purpose: to assess the feasibility and outcomes generated by a technology transfer of the Matrix treatment model for methamphetamine (MA) abuse into several community-based treatment programs, and specifically to compare outcomes of treatment as usual at each site with… (More)
UNLABELLED Permutation test is a popular technique for testing a hypothesis of no effect, when the distribution of the test statistic is unknown. To test the equality of two means, a permutation test might use a test statistic which is the difference of the two sample means in the univariate case. In the multivariate case, it might use a test statistic… (More)
BACKGROUND Universally accepted landmark stages are necessary to highlight key events in plant reproductive development and to facilitate comparisons among species. Domestication and selection of tomato resulted in many varieties that differ in fruit shape and size. This diversity is useful to unravel underlying molecular and developmental mechanisms that… (More)
