True - The relationship that links the predictors is highly non-linear. - 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. - 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). - The logit function is the log of the ratio of the probability of success to the...

1. If there are variables that need to be used to control the bias selection in the model, they should forced to be in the model and not being part of the variable selection process. - Answer-True 2. Penalization in linear regression models means penalizing for complex models, that is, models with a large number of predictors. - Answer-True 3. Elastic net regression uses both penalties of the ridge and lasso regression and hence combines the benefits of both. - Answer-True 4. Variable sele...

Nonparametric tests, categorical and ordinal data Complete Final Quiz Updated Questions and Answers 100% A+ Graded What are parametric tests? - CORRECT ANSWER-t-test, z-test, ANOVA Tests hypotheses regarding population parameter (means) Assumptions: sample is drawn from an approximately normal distribution. Confirm with statistic tests (Shapiro Wilks; Anderson Darling), look at distribution (frequency histogram),some non-normality can be tolerate (robust against departures from normalit...

Amanda is measuring the temperature. She looks at the thermometer and sees that it is somewhere between 65 and 66 degrees Fahrenheit. She is okay with the temperature in between two integers because she knows temperature is not ________ data, but temperature is _________ data.  a) Nominal, Ordinal  b) Nominal, Discrete  c) Continuous, Discrete  d) Discrete, Continuous Feedback: The correct answer is D. Temperature is not a measure that comes in increments (discrete) but is co...
