ISYE 6414 – Final Exam Questions and Answers 100% Correct 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...

2 x 2 table Correct Answer Top vs Side: Disease vs Exposure Reality vs Test Result A,B,C,D (Left to Right, Top to Bottom) Sensitivity Correct Answer A/(A+C) or TP/(TP+FN) Specificity Correct Answer D/(D+B) or TN/(TN+FP) PPV Correct Answer A/(A+B) or TP/ (TP+FP) NPV Correct Answer D/(D+C) or TN/ (TN+FN) Relative Risk Correct Answer A/(A+B) / C/(C+D) Use in Cohort Remember: In RR you are looking forward at risk of a disease/outcome in the *exposed vs unexposed groups* ...

This document contains my notes of the knowledge clips, my notes of the lecture, my notes of my workgroup meeting & summaries of the mandatory literature.

Complete summary of all content of the Statistical Modelling in Medical Research course (BMs61). This includes a clear description of linear regression and logistic regression, as well as two types of variable selection; backwards elimination and forward selection. The summary provides a description of how to make these models and how to test whether a new model has higher prediction. Odds ratio calculations for logistic regression are provided as well.

CPH Exam Questions & Answers 2023/2024 Host, agent and environment - ANSWER-The epidemiologic triangle (triad) describes the occurrence of disease as an interaction between what three factors? -0.9 An odds ratio of -0.9 most strongly indicates a computational error because an odds ratio is calculated using probabilities, which cannot be negative. An odds ratio is the probability that an event will occur divided by the probability that it will not occur. Since probabilities cannot be n...
