previous years (EXHIBIT A). We see that 1977 and 1978 show unusually high sales. This can imply that sales do not necessarily depend on time. This is confirmed by a regression of sales in $ with time. Even though the R-squared value is not low 56.9%‚ the actual sales for 1978 does not lie in the 95% confidence interval predicted our regression (=(-7016.76 + 129.2*78 + 2(619))) (EXHIBIT B). From reading the case study‚ price seems to be a big factor determining sales. The Brazil frost disaster that

Model To Be Studied By Residual 1. The regression function is not linear. 2. The error terms do not have constant variance. 3. The error terms are not independent. 4. The model fits all but one or few outliers‚ 5. The error terms are not normally distributed. 6. One or several important predictor(s) have been omitted from the model. Diagnostic For Residuals Six diagnostic plots to judge departure from the simple linear regression model * Plot of residuals against predictor

Regression with a Binary Dependent Variable Binary Dependent Variables and the Linear Probability Model • • • Many of the decisions made by people are binary. What factors drive a person’s decision? This question leads to regression with a binary dependent variable. The binary choice problem is an example of models with limited dependent variables (see Appendix 9.3 for details). Note that the multiple regression model discussed earlier does not preclude a dependent variable from being binary
