Modified cramer-von mises and anderson-darling tests for weibull distributions with unknown location and scale parameters

The standard Cramer-von Mises and Anderson-Darling goodness-of-fit tests require continuous underlying distributions with known parameters. In this paper, tables of critical values are generated for both tests for Weibull distributions with unknown location and scale parameters and known shape parameters. The powers of the Cramer-von Mises, Anderson-Darling, Kolmogorov-Smirnov, and Chi-Square tests for this situation are investigated. The Cramer-von Mises test has most power when the shape is 1.0 and the Anderson-Darling test has most power when the shape is 3.5. Finally, a relation between critical value and inverse shape parameter is presented.     

IN SEARCH OF WHAT IS RIGHT: THE MORAL DIMENSIONS OF THE DRUG DEBATE

The protagonists in the drug debate are talking past one another. While some argue that the drug debate is a health and social issue and should primarily be analytical and based on empirical evidence, others, explicitly or implicitly, treat it as a moral issue: overwhelmingly, in Australia, based on Christian beliefs. The aim of this paper is to set out a framework for the debate which explicitly recognises its moral as well as its empirical and analytical dimensions. It is hoped that greater transparency will facilitate the debate and may help the formulation of common positions. Heroin maintenance is used as an example to illustrate the arguments.     

Relationships Between Parenting Environment and Children's Mental Health Among African American and European American Mothers and Children

This study examined the relationship between aspects of the parenting environment and children's conduct problems and anxious symptoms among socioeconomically comparable samples of African American and European American mothers and their kindergarten children. Ethnic differences in parenting may lead to differences in the relationship between parenting and child outcomes. Thus, the moderating role of ethnicity for the relationships between parenting and children's mental health was tested. African American and European American parents were similar in their parenting practices. European American children reported a higher number of anxious symptoms, however. Parenting and family interaction patterns were associated with children's anxious symptoms and conduct problems. Although many relationships were similar across ethnic groups, there were ethnic differences in the relationships between maternal parenting efficacy and anxiety and between hostile control and conduct problems. These similarities and differences are discussed in light of theory and familial, cultural, and environmental niches.     

The effect of attitudes on emotional reactions to expressive displays of political leaders

One hundred subjects participated in an experiment to assess emotional reactions to the expressive displays of political leaders. Attitudes were assessed through questionnaire items, and facial EMG, heart rate, and skin conductance were recorded while subjects watched silent expressive displays of intense happiness/reassurance, mild happiness/reassurance, and anger/threat by President Reagan and Senator Hart. Half of the subjects reported their global affective reaction during each display, and all subjects reported discrete emotional reactions following each display. For Reagan, main effects were found for display type and for prior attitude in the self-report scales and in facial EMG, although significant Prior Attitude X Display interactions indicated that the intense happiness/reassurance displays most strongly differentiated supporters from opponents. Main effects were found for Hart's displays on the self-report scales and on facial EMG, and post hoc analyses revealed attitude effects. These results support previous research concerning affective reactions to dynamic expressive displays of emotion, but they also show the possible influence of prior attitude toward the expressor on both somatic and subjective measures of emotional response.This research was supported by National Science Foundation Grant SES 83-10176 and the Lincoln Filene Endowment to Dartmouth College and was part of a collaborative project involving Professors Roger D.
