A new method to estimate longevity risk based on the kernel estimation of extreme quantiles truncated age-at-death distributions is proposed. Its theoretical properties are presented and a simulation study reported. The flexible yet accurate conditional having survived certain age fundamental for evaluating lifetime insurance. Our proposal combines parametric with nonparametric sample informati...

down in the trenches and barter for access to taxpayer dollars. Figuring out which agency programs deserve these scarce resources is in many ways the government's chief responsibility. It's a tough job made even more so by all the political maneuvering that goes on in the nation's capital. To help make fair decisions, the government needs an unbiased watchdog, free of political affiliations, to...

The technique introduced in this paper is a means for estimating and discovering underlying patterns for a large number of curves observed with heteroscedastic errors. Therefore, both the mean and the variance functions of each curve are assumed unknown and varying over time. The method consists of a series of steps. We transform using an orthonormal basis of functions in L2. In the transform d...

In this paper the problem of estimating a covariance matrix parametrized by an irreducible symmetric cone in a decision-theoretic set-up is considered. By making use of some results developed in a theory of finite-dimensional Euclidean simple Jordan algebras, Bartlett’s decomposition and an unbiased risk estimate formula for a general family of Wishart distributions on the irreducible symmetric...

In NLP, we need to document that our proposed methods perform significantly better with respect to standard metrics than previous approaches, typically by reporting p-values obtained by rankor randomization-based tests. We show that significance results following current research standards are unreliable and, in addition, very sensitive to sample size, covariates such as sentence length, as wel...

A prevalent stereotype is that people become less risk taking and more cautious as they get older. However, in laboratory studies, findings are mixed and often reveal no age differences. In the current series of experiments, we examined whether age differences in risk seeking are more likely to emerge when choices include a certain option (a sure gain or a sure loss). In four experiments, we fo...

Sequential risk-taking tasks, especially the Balloon Analogue Risk Task (BART), have proven powerful and useful methods in studying and identifying real-world risk takers. A natural index in these tasks is the average number of risks the participant takes in a trial (e.g., pumps on the balloons), but this is difficult to estimate because some trials terminate early because of the consequences o...

BACKGROUND Cardiovascular disease (CVD) will remain the predominant cause of death and a major cause of morbidity for the foreseeable future. Consequently, CVD prevention offers the greatest potential for the prevention of premature mortality and the compression of morbidity. DISCUSSION The 2013 guidelines of the American College of Cardiology and the American Heart Association expand the eli...
