More Multiple Regression:
Database #1:
This Regression Model is from the Manufacturing Database to predict Cost of Materials by Number of Employees, New Capital Expenditures, Value Added by Manufacture, and End of Year Inventories. The model is somewhat strong; as the r-squared is .609; the f test and the significance are at decent levels. Some of the variables are stronger predictors then others as you can see in the t-stat and the p value; the best predictor is the value added by Manufacture.
Database #2:
Regression Model using the financial database: This regression model is weak! The variables that seem to be the best predictors are the Dividends per Share and the Total Assets. As you can see the r-squared is very low; the f test and the significance are weak.
Database #3: International Stock Market Database:
This regression model is fairly significant; and med-strong. The r-squared; the f-test and the significance of f are all med-strong. There are a few predictors that are better than others, the predictors that are good for this regression model are: the FTSE; DJIA; and the Hang Seng.
Database #4:
Annual Food Spending by Annual Income and Non-Mortgage Household Debt Regression Model. The model is decent in strength. The f test is really good, and so is the significance of f. The predictor that seems stronger is the annual household income; because its T-stat and P value were better, when I ran a regression model for just the annual household income and the annual food spending the regression model didn’t change very much.
