The increase of the expected lifetime, that is the longevity phenomenon, is accompanied by an increase of the number of seniors with a severe disability. Because of the significant costs of long term care facilities, it is important to analyze the time spent in long term care, as well as the...

This survey is devoted to the statistical analysis of duration models and pointprocesses. The first section introduces specific concepts and definitions forsingle-spell duration models. Section two is devoted to the presentation ofconditional duration models which incorporate the effects of...

This paper reviews the fund ratings based on Sharpe performance measures. We define a battery of performance measures in a mean-variance framework. They differ by the information taken into account in their computation, but also by the potential use of the fund by the investor. We apply these...

We define a battery of Sharpe performance measures, which differ by the information taken into account in their computation, but also by the potential use of the fund by the investor. Four advantages of Sharpe performance based rating are especially important for the investor. First, the...

This paper introduces a new parametric fund performance measure, called the L-performance. The L-performance is an alternative to the Sharpe performance, which is commonly used in practice despite its inability to account for skewness and heavy tails of unconditional return distributions. The...

This paper presents a new general class of compound autoregressive (Car) models for non-Gaussian time series. The distinctive feature of the class is that Car models are specified by means of the conditional Laplace transforms. This approach allows for simple derivation of the ergodicity...
