Linear regression. Regression: predicting a continuous value. Logistic regression. Classification: predicting a discrete value. Gradient descent. Very general optimization technique. Regression wants to predict a continuous-valued output for an input.. 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. 2. Dr. Alok Kumar. Logistic regression applications. Dr. Alok Kumar. 3.
