In WLS, you . are simply treating each observation as more or less informative about the underlying relationship between X and Y. Those points that are more informative are given more 'weight', and those that are less informative are given less weight. Logistic Regression. Important analytic tool in natural and social sciences. Baseline supervised machine learning tool for classification. Is also the foundation of neural networks. Generative and Discriminative Classifiers. 2. Dr. Alok Kumar.
