✦ Synopsis

Rank correlation measures are de®ned for directional data based on measures of distance. Angular± angular as well as angular±linear correlations are considered. Asymptotic distributions are obtained for statistics based on Spearman and Kendall measures under the null hypothesis of no association. The results are applied to two sets of data. The ®rst consists of pairs of wind directions, whereas the second involves data on wind directions and ozone.

McNemar's test is often used to compare two proportions estimated from paired observations. We propose a method extending this to the case where the observations are sampled in clusters. The proposed method is simple to implement and makes no assumptions about the correlation structure. We conducted

Analysis of covariance is an effective method for addressing two considerations for randomized clinical trials. One is reduction of variance for estimates of treatment effects and thereby the production of narrower confidence intervals and more powerful statistical tests. The other is the clarificat

Subjects often drop out of longitudinal studies prematurely, yielding unbalanced data with unequal numbers of measures for each subject. A simple and convenient approach to analysis is to develop summary measures for each individual and then regress the summary measures on between-subject covariates
