Inferences about Interclass and Intraclass Correlations from Familial Data,ood ratio test is proposed for testing the equality of intraclass correlations in two multivariate normal populations. The asymptotic null distribution of the proposed test statistic is obtained. A test procedure based on Fisher’s .-transformation is also discussed.

Learning Search Control KnowledgeTwo univariate methods of estimation in parabolic bioassays are reviewed, and a new test for the assumption of “parallelism” is proposed. One method is extended into a multivariate situation based on a general linear model which generates a point estimator and approximate confidence limits for the associated relative potency.

Recursive Partition: A Versatile Method for Exploratory-Data Analysis in Biostatistics,..We will also tackle the general problem of evaluating the statistical soundness of exploratory analyses. The use of cross-validation, bootstrapping and model selection criteria, such as the Akaike Information Criterion, will be discussed.

Statistical Ramifications of Linear Analogue Scales in Assessing the Quality of Life of Cancer Pati Our patient population produced reliable test-retest results that were stable for both factor analysis and multivariate regressions. Also, we can report the results of some sample size investigations for both reliability and stability of data collected in this and other studies.

,Point Estimation of the Odds Ratio in Sparse 2 × 2 Contingency Tables,mples with known probabilities of “success” in each. The mean, variance, bias, mean squared error and average absolute error of each of the estimators are obtained and compared. Contrary to previous simulation work in 2 × 2 × . tables, it is found that the unconditional MLE is usually preferred to t
