Engaged couples who took a premarital inventory called FOCCUS were contacted 5 years later to see if their scores would predict their future marital success. Results showed that FOCCUS successfully predicted the future marital success of most couples, supporting the predictive validity of FOCCUS. The results also indicate that FOCCUS and PREPARE are roughly comparable in terms of their predictive validity. 相似文献

There is a growing movement towards the construction of statistical expert systems by statisticians to assist incertain aspects of their work. As one of the most'abused’ areas, experimental design could benefit from a system ofthis type. This paperoutlines some ideas on how a system for intelligently constructing designs could be built. 相似文献

The study described in this article was designed to determine the effects of childcare involvement on the lifestyles of fathers with young children. One hundred and twenty-seven separated or divorced men were interviewed. Their parental responsibilities ranged from full custody or joint custody to weekends or monthly visits. For the most part these men represented a middle class, highly educated, urban population. The primacy of work and occupational roles in the lives of the fathers was challenged by the contractual obligations of parenting. Fathers who spent time with their children had the opportunity to work out some crisis issues of divorce such as control, interdependence, and self-image. It was found that postdivorce parenting is an important source of resocialization for men in areas of work orientation and personal relationships. It is expected that this new functioning will have positive effects on the structure of reconstituted (i.e., second marriage) families. 相似文献

In statistical process control applications, the multivariate T 2 control chart based on Hotelling's T 2 statistic is useful for detecting the presence of special causes of variation. In particular, use of the T 2 statistic based on the successive differences covariance matrix estimator has been shown to be very effective in detecting the presence of a sustained step or ramp shift in the mean vector. However, the exact distribution of this statistic is unknown. In this article, we derive the maximum value of the T 2 statistic based on the successive differences covariance matrix estimator. This distributional property is crucial for calculating an approximate upper control limit of a T 2 control chart based on successive differences, as described in Williams et al. (2006). 相似文献
