Presentation transcript:

DRQ 8 Dr. Capps AGEC 317 4 points What is the sum of all residuals equal to? (1 point) 0 How do you interpret these correlation coefficients? -0.001 (1/2 point) a very small negative correlation or linear association among two variables 0.9 (1/2 point) a very large positive correlation or linear association among two variables

DRQ 8 Dr. Capps AGEC 317 4 points __Principle of Parsimony(definition)___ simple models are generally preferred to complex models, especially in forecasting (1 point) What are two of the four assumptions of a regression model? Constant variance of the error term No correlation of the error term at observations i and j No correlation of the error term with any explanatory variable The mean of the error term is equal to 0
