Introduction: Estimation of stature is one of the most important fields in forensic medicine. Also it is of particular interest to anthropologists and anatomist. Our aim was to investigate the relationship between stature and the length of lower limb and foot to derive a regression formula for estimating the stature. Methods: Three anthropometric measurements Stature, Lower Limb Length (LL...
Many parameters and positive-definiteness are two major obstacles in estimating and modelling a correlation matrix for longitudinal data. In addition, when longitudinal data is incomplete, incorrectly modelling the correlation matrix often results in bias in estimating mean regression parameters. In this paper, we introduce a flexible and parsimonious class of regression models for a covariance...
the world wide web becomes very popular recently and plays an influential role in english learning. by burgeoning role of source-based writing as partial fulfillment of tefl courses and vast use of the internet, lack of empirical studies to explore these areas is obvious. this study aimed to explore the effect of the amount of familiarity with the web (internet literacy) on junior english stude...
The article considers the problem related to correlation and regression analysis. use of analysis methods is shown in specific example illustrating study a particular economic situation. Special attention paid Excel Analysis Package, which significantly simplifies solution from computational standpoint.
