What is the difference between simple linear regression and multiple linear regression? What is the difference between multiple linear regression and logistic regression? Why should you use adjusted R-squared to choose between models instead of R- squared? Use SPSS to: Height (Xi) Diameter (Yi) 70 8.3 72 10.5 75 11.0 76 11.4 85 12.9 78 14.0 77 16.3 80 18.0 Create a scatterplot of the data above. Without conducting a statistical test, does it look like there is a linear...

When we estimate a linear multiple regression model (including a linear simple regression model), it appears that the calculation of the coefficient of determination, R2, for this model can be accomplished by using the squared sample correlation coefficient between the original values and the predicted values of the dependent variable of this model. Is this statement true? If yes, why? If not, why not? Please use either matrix algebra or algebra to support your reasoning.

Discuss the underlying assumptions of a simple linear regression model; multiple regression model; and polynomial regression.

You are developing a simple linear regression analysis model. The simple correlation coefficient between y and x is -0.72. What do you know must be true about b1. The least squares estimator of B1? Why? In a multiple linear regression analysis with k = 3. From the t test associated with B1, you conclude that B1 = 0. When you do the f test will you reject or fail to reject the null hypothesis? Why? In a simple bilinear regression...
