摘要:

AbstractIn this paper we describe the principle of external pivoting, a variant of the primal simplex algorithm. Its validity is proved in general and various strategies are designed which are based on this principle. The average convergence behavior for these strategies is then tested in a series of randomly generated problems. It is found that at least one of the strategies compares favorably with the regular simplex method.

摘要:

AbstractVarious models have been proposed as bivariate forms of the exponential distribution. A brief but comprehensive review is presented which classifies, interrelates and contrasts the different models and outlines what is known about distributional properties, applicability and estimation and testing of parameters (particularly the association parameter). Some new results are presented for one particular model. Maximum likelihood, and moment–type, estimators of the association parameter are examined. Asymptotic variances are derived and attention is given to the relative efficiency of the estimators and to problems of their evaluatio

This fact can be interpreted in terms of a certain limit theorem for a sequence of i.i.d Bernoulli

摘要:

AbstractA displaced Poisson process model allowing for stratified populations and “false negatives” is presented for describing the progress of certain chronic diseases. This model, which builds on earlier work by the authors, allows for the simple estimation of various parameters and distributions of interest in screening. A Monte Carlo simulation study illustrating and partially verifying the model predictions is gi
