摘要: We consider the multiple regression model under classification of the dependent variable. An ML estimator for the model parameters is constructed, and sufficient conditions for strong consistency and asymptotic normality are proved. Theoretical results are illustrated by computer simulations....

Using a conceptual and nontechnical approach, the meaning of structural equation modeling (SEM) and the similarities to, and differences from, more commonly used procedures such as correlation, regression, path analysis, and factor analysis are explained. Application of the statistical technique is pres...
In addition, the Multiple-Linear-Regression (MLR) method is applied on the extracted training sample points to estimate the illumination surface. Furthermore, the estimated illumination surface is used to normalize the non-uniform light of the image to binarize the image using Otsu’s global ...
