Some statistical estimation problems in ruin theory
Much research in ruin theory in insurance mathematics focuses on the behaviour of various quantities of interest, such as the probability of ruin or the ruin-time moments, for a particular risk model in insurance. In practice, precise knowledge of the risk model is available only via observed data. In this presentation, the problem of statistical estimation of the quantities of interest, given ...
متن کاملOn some reliability estimation problems in random and partition testing
Studies have shown that random testing can be an effective testing strategy. One of tbe goals of testing is to estimate the reliability of tbe program from tbe test outcomes. In tbis paper we extend tbe Tbayer-Lipow-Nelson reliability model to account for tbe cost of errors. Also we compare random with partition testing by looking at upper confidence bounds for the cost weighted performance of ...
متن کاملOn some parameter estimation problems in alpha-stable processes
Current algorithms for estimating the parameters of a symmetric alpha-stable ARMA process are either highly non-linear, or assume small MA orders (q 3), or invoke the minimum-phase assumption. We use results from the statistics literature to show that the normalized correlation is well-de ned; we show that the normalized cumulants are also well-behaved. We propose to use the correlation to esti...
متن کاملSome controversial multiple testing problems in regulatory applications.
Multiple testing problems in regulatory applications are often more challenging than the problems of handling a set of mathematical symbols representing multiple null hypotheses under testing. In the union-intersection setting, it is important to define a family of null hypotheses relevant to the clinical questions at issue. The distinction between primary endpoint and secondary endpoint needs ...
متن کاملSome multiple-time-scale problems in molecular dynamics.
Many physical problems, particularly in chemical and biological systems, involve processes that occur over widely varying time scales. Such problems have motivated the development of new methods for treating multiple-time-scale problems in molecular dynamics (MD). Methods have been developed for determining the vibrational frequencies and normal modes of large systems in full and reduced confor...
متن کاملPost hoc power estimation in large-scale multiple testing problems
BACKGROUND The statistical power or multiple Type II error rate in large-scale multiple testing problems as, for example, in gene expression microarray experiments, depends on typically unknown parameters and is therefore difficult to assess a priori. However, it has been suggested to estimate the multiple Type II error rate post hoc, based on the observed data. METHODS We consider a class of...
