We consider the problem of estimating a Major League Baseball players batting average in the second half of a season based on his performance in the first half. We fit two linear regression models to players averages from each half of the 2004 season, use these models to predict batting averages...

We propose a method to detect the existence of quantitative trait loci (QTL) in a backcross population using a score test. Since the score test only uses the MLEs of parameters under the null hypothesis, it is computationally simpler than the likelihood ratio test (LRT). Moreover, because the...

In the first stage of a two-stage, drop-the-losers design, a candidate for the best treatment is selected. At the second stage, additional observations are collected to decide whether the candidate is actually better than the control. The design also allows the investigator to stop the trial for...

Specific theoretical conditions for the success or failure of extended immediate deterrence (EID) are identified based on assumptions about rational action. The resultant decision theoretic model yields four hypotheses which are tested against cases of EID between 1885 and 1970. The hypotheses...
