Extensions of multiple linear regression

Many statistical methods are linked together through their connection with weighted least squares and hence regression. This article reviews these connections, emphasising the iteratively weighted least squares algorithm.     

Some results on interval estimation for the two-parameter weibull or extreme-value distribution

Two statistics based on simple, closed form estimators are examined for use in interval estimation of reliability and of the location parameter of the extreme-value distribution. Properties of the estimators are studied by Monte Carlo simulation, and procedures for interval estimation and tests of hypotheses for the location parameter and reliability are provided.     

Bayesian adaptive bandit-based designs using the Gittins index for multi-armed trials with normally distributed endpoints

Adaptive designs for multi-armed clinical trials have become increasingly popular recently because of their potential to shorten development times and to increase patient response. However, developing response-adaptive designs that offer patient-benefit while ensuring the resulting trial provides a statistically rigorous and unbiased comparison of the different treatments included is highly challenging. In this paper, the theory of Multi-Armed Bandit Problems is used to define near optimal adaptive designs in the context of a clinical trial with a normally distributed endpoint with known variance. We report the operating characteristics (type I error, power, bias) and patient-benefit of these approaches and alternative designs using simulation studies based on an ongoing trial. These results are then compared to those recently published in the context of Bernoulli endpoints. Many limitations and advantages are similar in both cases but there are also important differences, specially with respect to type I error control. This paper proposes a simulation-based testing procedure to correct for the observed type I error inflation that bandit-based and adaptive rules can induce.     

Labour Force Participation,Social Inclusion and the Fair Work Act: Current and Carbon‐Constrained Contexts

The notion that employment is a precondition for personal wellbeing and social inclusion is almost sacrosanct in Australian culture. Yet, the working and living conditions of Australia's low paid workers tells a different story. While labour market participation is a cornerstone of the Federal Government's Social Inclusion Agenda, it is recognized that low pay and poor job quality often derail this key objective. Indeed, the difficulty of ‘making work pay’ at the bottom end of the labour market is a social inclusion challenge that has yet to receive the policy or public attention that it warrants. This article considers what the Fair Work Act means for the social inclusion of disadvantaged workers, in the context of wider‐ranging strategies to address low pay. It concludes with some considerations of the challenges that a carbon‐constrained economy is likely to present for labour force participation as a remedy for social exclusion.     

基于社会契约理论的动物伦理——对努斯帕姆的回应

在《正义的前沿》一书中,玛莎.努斯帕姆认为,社会契约理论无法容纳针对动物的政治义务,因为社会契约理论要求各缔约方需要具备大致等同的体能和精神条件。但是她对社会契约传统的阐释并不令人信服。社会契约理论只要求缔约方具有同等的自由、应当受到同等的道德考量。社会契约理论之所以优于努斯帕姆提出的能力方法（capabilities approach）在于,社会契约理论将针对动物的正义共同体的范围限定在我们能够认可的正义主体、以及与我们拥有政治关系的范围之内。     

Sexual Harassment in Public Places: Experiences of Canadian Women*

Des chercheurs ont étudié les cas de harcèlement sexuel en milieu de travail et dans les universités. En collaboration avec des experts judiciaires, ils ont conceptualisé le harcelement sexuel et en ont fait une question de droits de la personne. Notre recherche, fondée sur un sondage effectue en 1992 auprès de 1 990 femmes canadiennes, réVéle que le harcèlement sexuel se produit aussi dans les lieux publics. Nous présentons des données inédites sur le sujet en exa-minant le type, la fréquence et la gravité du harcèlement, les carac-téristiques des femmes le plus susceptibles d'être harcetées, les implications pouvant servir à bâtir une théone sur le harcèlement dans les lieux publics, les réactions des femmes a l'égard du harcèlement ainsi que ses conséquences sur les plans émotionnel et psychologique. Researchers have expended much effort studying sexual harassment in the workplace and universities. Together with legal experts, they have conceptualized sexual harassment as a human-rights issue: a form of sexual discrimination that typically occurs in relationships of unequal power. Our research, based on a 1992 survey o{ 1,990 Canadian women, suggests sexual harassment is also prevalent in public places such as streets, transit systems and malls. We supply rare data about sexual harassment in public places by examining the types, frequency, and severity of harassment; the characteristics of women most likely to be harassed; the theoretical implications of public harassment; women's responses to harassment; and its emotional and psychological effects.     

Properties and Applications of the Generalized Likelihood as a Summary Function for Prediction Problems

The generalized likelihood plays an important role in parametric inference for prediction and empirical Bayesian models. This paper emphasizes the utility of the generalized likelihood as a summarization procedure in general prediction models. Properties of the generalized likelihood when used in this setting, and examples of its use as a data analytic tool are given in a series of numerical examples.
