Bimodality and the sudden jump, certainly when they are tested by regression analysis and mixture distributions, are not unique for the cusp model. It is very difficult to differentiate acceleration and cusp models by these flags. Inaccessibility changes this statement somewhat. It is unique, but ...

A t table such as Table 1.8.1 is used to find values of the t statistic where v is located along the vertical margin and the probability is given on the horizontal margin. (For a one-tailed test, given the probability for the left tail, the t value must be preceded by a negative ...

The win ratio has been widely used in the analysis of hierarchical composite endpoints, which prioritize critical outcomes such as mortality over nonfatal, secondary events. Although a regression framework exists to incorporate covariates, it is limited
8.2.8 Regression and Explanatory Variables It is often useful or important to have a model in which one or more of the elements of θ are allowed to be functions of explanatory variables. This is a generalization of statistical “regression analysis” in which the most common models have the...
