We introduce a unified approach for testing variety of rather general null hypotheses that can be formulated in terms covariance matrices. These include as special cases, example, equal variances, traces, or elements the matrix taking certain values. The proposed method only requires very few assumptions and thus promises to broad practical use. Different test statistics are defined, their asym...

The main goal of this paper is to study residuals in a special case the extended growth curve model, called GMANOVA–MANOVA model. With help an example, emphasis put on model formulation, interpretation and that vanish, with discussion about reasons behind fact consequence it.

This study investigated, both histologically and histometrically, the efficacy of enamel matrix derived proteins (EMD) associated with bioactive glass (BG) and an absorbable membrane in the treatment of class III furcation defects in mongrel dogs. After surgical defect creation and chronification, the lesions were randomly divided into three groups according to the treatment employed: Test Grou...

Gender differences among children and adolescents were examined on 14 separate measures of short-term memory. A nationally stratified sample of 1,279 children and adolescents, 637 males and 642 females, ranging in age between 5 and 19 years, were assessed on the 14 subtests of the Test of Memory and Learning (TOMAL). Factor structure of the TOMAL was determined to be invariant as a function of ...

The study examined the relationships between work experience and (a) safety perceptions, (b) job satisfaction, (c) compliance with safety management policies and (d) accident frequency. Participants were Ghanaian industrial workers (N = 320). They were divided into 2 cohorts: experienced and inexperienced workers. Workplace safety perceptions were assessed with Hayes et al.'s 50-item work safet...

A multivariate normal statistical model defined by the Markov properties determined by an acyclic digraph admits a recursive factorization of its likelihood function (LF) into the product of conditional LFs, each factor having the form of a classical multivariate linear regression model (≡ MANOVA model). Here these models are extended in a natural way to normal linear regression models whose LF...
