Contingency tables 1. Researchers wanted to study if couples having children are married. They surveyed a large group of people. The data are shown in the contingency table below. What is the relative risk of having children for those who are married? Round your answer to two decimal places. Children no children total Married – 97 35 132 Not married- 68 71 139 Total 165 106 271 1.50 The probability that someone who is married has children is 97/132. The probability that someone who ...

Define RR and OR - correct answer RR- likelihood someone exposed to risk factor will develop disease, compared with one not exposed (incidence in exposed, incidence in not exposed) OR- estimate of RR Interpret RR and OR - correct answer RR - Nul value (=1)- indicates risk of disease is identical between those exposed and those not exposed - >1= positive association/increased risk among those expo...

CPH EXAM STUDY GUIDE EXAM REVIEW QUESTIONS AND ANSWERS, RATED A+ epidemiological triad host, agent, environment An _______ is the probability that an event will occur divided by the probability that it will not occur. Since probabilities cannot be ______, a negative odds ratio would indicate computational ______. odds ratio, negative, error _______ is the proportion of truly diseased people in the screened population who are identified as having the disease by the screening test.

CPH EXAM REVIEW QUESTION AND ANSWERS, GRADED A+/ VERIFIED/ ALL EXAMINABLE QUESTIONS/ TESTBANK QUESTIONS/ Which of the following estimates of an odds ratio most strongly suggests a computational error? 1) 7.8 2) 1.2 3) -0.9 4) 20.9 3) -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 wil...

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...

CFA Level 1 - 101 Must Knows 368 Questions with Verified Answers Addition Rule of Probability - CORRECT ANSWER ADDITION: P(A or B) = P(A) + P(B) - P(AB) Roy's Safety First Criterion - CORRECT ANSWER Safety First Ratio = (E(R) - Rₜ) / σ Larger ratio is better If (Rₜ) is risk free rate, then it becomes Sharpe Ratio Sharpe Ratio - CORRECT ANSWER Sharpe Ratio = (E(R) - RFR) / σ Larger ratio is better If (Rt) is higher than RFR, then it becomes Safety First Ratio Centra...
