Structured orthogonal families of one and two strata prime basis factorial models

The models in structured families correspond to the treatments of a fixed effects base design \(\pi \) . Then the action of factors in \(\pi \) , on the fixed effects parameters of the models, is studied. Analyzing such a families enables the study of the action of nesting factors on the effects and interactions of nested factors. When \(\pi \) has an orthogonal structure, the family of models is said to be orthogonal. The models in the family can have one, two or more strata. Models with more than one stratum are obtained through nesting of one stratum models. A general treatment of the case in which the base design has orthogonal structure is presented and a special emphasis is given to the families of prime basis factorials models. These last models are, as it is well known, widely used in fertilization trials.     

A simple test for new better than used in expectation

We present a statistical procedure to test that a life distribution is exponential against the al ternative that it is continuous new better than used in expectation. The test is shown to be consistent and asymptotic relative efficiency resul ts are obtained against the competitor developed earlier by Hollander and Proschan [2], for certain families of alternatives.     

Full Bayesian Significance Test for Zero-Inflated Distributions

ABSTRACT

In this article we propose a new Kolmogorov-Smirnov type test for testing the nonlinearity of time series, based on the one which was originally introduced by An and Cheng. Our simulation study shows that the suggested test performs better than the original test. An associated bootstrap test is also found to outperform remarkably the non-bootstrap test.     

A Bayesian analysis of the Conway–Maxwell–Poisson cure rate model

The purpose of this paper is to develop a Bayesian analysis for the right-censored survival data when immune or cured individuals may be present in the population from which the data is taken. In our approach the number of competing causes of the event of interest follows the Conway–Maxwell–Poisson distribution which generalizes the Poisson distribution. Markov chain Monte Carlo (MCMC) methods are used to develop a Bayesian procedure for the proposed model. Also, some discussions on the model selection and an illustration with a real data set are considered.     

Caught in a “Bad Romance”? Reconsidering the Negative Association Between Sociosexuality and Relationship Functioning

Sociosexuality refers to individual differences in interest and willingness to engage in sexual activity without an emotional connection. Unrestricted sociosexuality is associated with a greater likelihood of infidelity and with poorer relationship quality. However, previous research has failed to examine relationship-specific characteristics that may moderate these findings. Two studies of romantically involved adults examined whether relationship commitment and different relationship agreement types moderate the associations between unrestricted sociosexuality and infidelity. Study 1 (N = 300) showed that individuals in consensual monogamous (CM) relationships with extradyadic sex (EDS) experiences were more sociosexually unrestricted than individuals without such experiences. The positive association between unrestricted sociosexuality and EDS emerged only for less, but not more, committed individuals. Study 2 (N = 270) replicated these results. Furthermore, results showed that individuals in consensual nonmonogamous relationships (CNM) relationships were the most sociosexually unrestricted, but no differences emerged in relationship commitment or satisfaction, when compared to individuals in CM relationships without prior EDS. Individuals in CM relationship with prior EDS were the least committed and satisfied. The negative association between unrestricted sociosexuality and both relationship quality indicators emerged for all individuals in CM relationships, but it was nonsignificant for individuals in CNM relationships. Implications are discussed.     

Conditional tests for elliptical symmetry using robust estimators

This paper presents a procedure for testing the hypothesis that the underlying distribution of the data is elliptical when using robust location and scatter estimators instead of the sample mean and covariance matrix. Under mild assumptions that include elliptical distributions without first moments, we derive the test statistic asymptotic behavior under the null hypothesis and under special alternatives. Numerical experiments allow to compare the behavior of the tests based on the sample mean and covariance matrix with that based on robust estimators, under various elliptical distributions and different alternatives. We also provide a numerical comparison with other competing tests.     

Perceptions of health and well-being in transition societies: some results of a qualitative study carried out in the Ukraine

This article reports on research carried out within the scope of the Inco-Copernicus Programme, from 1999 to 2002, on ‘Health and Well-Being in Transition Societies’. In particular, it presents the results of a qualitative study carried out in the Ukraine. On the basis of in-depth interviews and two biographical interviews, data are analysed on the following topics: employment situation, informal economy, perception of health and well-being, perception of social services, perception of social exclusion, crisis and low expectations, coping strategies, and perceptions of citizens’ rights. It concludes that transition has meant important change that has had a significant effect upon the Ukrainian population.     

Some asymptotic results in finite populations

In this paper we investigate limiting properties of predictors of some finite population quantities. Both, the sample size and the population size are considered to become large. Limiting properties like consistency and asymptotic normality of the best linear unbiased predictors of the population total and of the finite population regression coefficient are investigated.

Sexual Offenses Against Elderly People: Forensic Evaluation and Judicial Outcome

Forensic evaluation reports and judicial outcomes regarding older victims of suspected sexual offenses were retrospectively reviewed. During this period, a total of 14 cases were registered, corresponding to 0.3% of nonfatal crimes against elderly and 0.6% of the total of sexual crimes reported. All the victims were female. The majority lived alone and did not have limitations in communication, orientation, ambulation, or autonomy. The offenders were all male (17 to 81 years old); most were known to the victims and had history of previous disruptive behaviors. The majority of the sexual offenses occurred in the victims’ homes, and the offenders tended to use physical violence. Forensic evaluation was crucial for the identification of physical and biological evidence, and forensic conclusions were positively correlated with the judicial outcome of each case. High prosecution and conviction rates were also observed.
