Question 1 1 / 1 pts Professor Alice studied the relationship between coffee drinking and myocardial infraction (MI) in young women aged 30-49 years. This retrospective study included 487 cases (Y=1) hospitalized for the occurrence of a MI, and 980 controls (Y=0) hospitalized for an acute condition (trauma, acute cholecystitis, acute respiratory diseases, and appendicitis). Each subject asked whether or not the daily consumption of five or more cups of coffee containing caffeine. The data ...

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). - Answer- The logit function is the log of the ratio of the prob...

Write a formal report on your findings from the last several weeks for the classification of the Santander Bank Case Study. The main objective is to write a fully executed R-Markdown program performing classification using the best models found for logistic regression, SVM, Random Forest and XGBoost algorithms, and comparing the values of their cost functions and accuracy scores. Make sure to describe the final hyperparameter settings of all algorithms that were used for comparison purposes. ...
