Given the widespread use of empirical actuarial risk tools in corrections and forensic mental health, it is important that evaluators and decision makers understand how scores relate to recidivism risk. In the current study, we found strong evidence for a relative risk interpretation of Static-99R scores using 8 samples from Canada, United Kingdom, and Western Europe (N = 4,037 sex offenders). ...

The performance of country exchange-traded funds and closed-end funds is investigated over the 2002 to 2011 period. Operating characteristics (i.e., expense ratios and portfolio turnover) and investment results (i.e., return, risk, and risk-adjusted return) are studied for investment funds with at least ten years of data. We find that although exchange-traded funds have significantly lower expe...

BACKGROUND To estimate relative risks or risk ratios for common binary outcomes, the most popular model-based methods are the robust (also known as modified) Poisson and the log-binomial regression. Of the two methods, it is believed that the log-binomial regression yields more efficient estimators because it is maximum likelihood based, while the robust Poisson model may be less affected by ou...

This paper presents a simple, intuitive theory of business risk. The results are used to explain empirical observations of Beaver on the power of various financial ratios to predict failure of firms, and to hypothesize improved predictive ratios for use in selecting attractive risk situations and in determining appropriate risk premiums.

This paper proposes an investment/capacity planning model for projects that involves the production of final products that are sold directly to consumers. The model considers some aspects of the problem that have not been put together before, namely, the location, the advertisement costs, and the effect of the competition. We have used a microbrewery capacity planning problem. The problem is fo...
