This paper presents a matrix formulation for log-linear model analysis of contingency tables. Both weighted least squares estimators and maximum likelihood estimators are considered in this fr~ework with results being given for their corresponding covariance matrix atructures. Moreover, a general analytical strategy is presented for the simultaneous use of(More)
A method in the current literature used to estimate the density of bacteria in a sample solution is the most probable number (MPN) procedure. This paper considers the change in density of bacteria in the sample through time. The MPN with its variance for a fixed time point is just one module of the experiment and is treated as a generalization of the(More)
BACKGROUND Echocardiography has been proposed as a method to screen children for rheumatic heart disease. The World Heart Federation has established guidelines for echocardiographic screening. In this study, we describe a rapid echocardiogram screening protocol according to the World Heart Federation guidelines in Samoa, endemic for rheumatic heart disease.(More)
