What can you say about the difference in R2 where R2 in a simple linear regression is 56% and in multiple regression R2 is 80%
1.) What is the difference between a simple regression model and a multiple regression model? a.) There isn’t one. The two terms are equivalent b.) A simple regression model has a single predictor whereas a multiple regression model has potentially many c.) A simple regression model can handle only limited amounts of data whereas a multiple regression model can handle large data sets d.) A simple regression is appropriate for a dichotomous outcome variable, whereas a multiple regression model should...

Part 2: Simple Linear Regressions – Chapter 14 (2 questions with a total of 11 sub-sections, 6 points per sub-section, part total 66 points) 2) A local grocery store wants to predict its daily sales in dollars (y). The manager believes that the amount of newspaper advertising (x) significantly affects sales. He randomly selects 7 days of data (n=7) consisting of daily grocery store sales (y, in thousands of dollars) and advertising expenditures (x, in thousands of dollars). The Excel...
2. In a typical simple linear regression model, explore the relationship between the expected value of change in the response variable y and the value of the regressor x changed by 20 or 40 units. Describe the condition or assumption, if any, to meet for such exploration. 3. In a multiple linear regression model where x1 and x2 are two regressors. Explore the relationship between the expected value of change in the response variable y and the value of the...
