ISYE 6414 Final Exam Review Questions and Answers 100% Pass Least Square Elimination (LSE) cannot be applied to GLM models. False - it is applicable but does not use data distribution information fully. In multiple linear regression with idd and equal variance, the least squares estimation of regression coefficients are always unbiased. True - the least squares estimates are BLUE (Best Linear Unbiased Estimates) in multiple linear regression. Maximum Likelihood Estimation is not applicable for...

This summary contains all the lecture notes of the course statistics 1 from year 1 of Psychology and Pedagogy. I included the text on the slides plus the comments of the professor so that you have a perfect overview of all the material for the exam. The book was really not needed for this exam because I got an 8 with only studying the lecture notes.

Logistic Regression - 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 - 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 the predict...
