Given a dataset for a response variable and a single regressor, we can fit the data using a regression model on the original values of the response variable or using a regression model on the ranks applied to the response variable. Discuss the advantages and the disadvantages of the two modeling approaches. Discuss the conditions required for either approach, respectively.

1) When we fit a model to data, which is typically larger? a) Test Error b) Training Error 2) What are reasons why test error could be LESS than training error? (Pick all that applies) a) By chance, the test set has easier cases than the training set. b) The model is highly complex, so training error systematically overestimates test error c) The model is not very complex, so training error systematically overestimates test error 3) Suppose we want to...

22. We fit a simple linear regression model using price (in dollars) to predict the number of packets of dog biscuits sold per day. The regression equation is y = 98.1 - 9.8x, and R2 = 0.5275. Explain how to interpret the R2 in the context of this problem.: * (A) 52.75% of the variation in the price is explained by the number of packets of dog biscuits sold per day. (B) 52.75% of the variation in the number of...

Q: A 95% confidence interval for the mean is (102, 106). If we test Ho: ? = 100 vs. H1: ? ? 100, the p-value will be: (A) larger than 0.05 (B) smaller than 0.05 (C) larger than 0.01 (D) smaller than 0.01 Q: Suppose you want to conduct a t-test using ? = 0.05. You take a random sample of size 30 and obtain the sample mean and sample standard deviation. As a result, you fail to reject the...
