ISYE 6414 Regression Modules 1-2 (2023/2024) Already Passed Assuming that the data are normally distributed, under the simple linear model, the estimated variance has the following sampling distribution: Chi-squared with n-2 degrees of freedom. The fitted values are defined as? The regression line with parameters replaced with the estimated regression coefficients. The estimators fo the linear regression model are derived by? Minimizing the sum of squared differences between the observed and ...

Logistic Regression - Answer-Commonly used for modeling binary response data. The response variable is a binary variable, and thus, not normally distributed. In logistic regression, we model the probability of a success, not the response variable. In this model, we do not have an error term g-function - Answer-We link the probability of success to the predicting variables using the g link function. The g function is the s-shape function that models the probability of success with respect to...
