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...

ISYE 6414 Final Exam; Questions and Answers 100% Verified True - The relationship that links the predictors is highly non-linear. Answer-In Logistic Regression, the relationship between the probability of success and the predicting variables is non-linear. False - In logistic regression, there are no error terms. Answer-In Logistic Regression, the error terms follow a normal distribution. True - the logit function is also known as the log-odds function, which is the ln(P/1-p). Ans...

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 ...

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...

Malampati III allows visualization of only the hard palate C. Malampati classifications are taken with the patient sedated and reclined D. Mallampati classifications of IV have greater odds ratio than Mallampati classifications of I for severe OSA - D. Mallampati classifications of IV have greater odds ratio than Mall...

1. The bacterium most likely to be transmitted from mother to infant during labor and cause neonatal sepsis is: a. Escherichia coli b. Staphylococcus aureus c. Group B Streptococcus d. Group A Streptococcus - Answer-Group B Streptococcus Rationale: In Group B Streptococcus (GBS) neonatal infections, heavy maternal colonization is associated with an increased risk for preterm labor, which in turn is a significant risk factor for neonatal infection. Intrauterine infection of the fetus th...
