- Input variables into Excel and run Regression analysis from the Data tab.
- List the following in determining best-fit model:
- Linear model between only x1-variable and y with correlation coefficient (r-squared) and SSE (Sum of Squares for Residual)
- Linear model between only x2-variable and y with correlation coefficient (r-squared) and SSE (Sum of Squares for Residual)
- Linear model between x1, x2 and y with correlation coefficient (r-squared) and SSE (Sum of Squares for Residual)
- Determine which model offers best fit and why (compare the Correlation coefficients and Sum of Squares of the residuals)
Using the best-fit model, list the following in determining significance:
- F-test: F-value and significance of linear model
- T-test for x1-variable: t-value and p-value for significance of variable
- T-test for x2-variable: t-value and p-value for significance of variable
Regression Output:
- List Variables
- Show Regression Output page
Linear Models:
- List three equations each with their r-squared and SSE values
- Compare r-squared and SSE values to determine which equation offers the best linear model
Significance Tests: For the best linear model state the following:
- F-test: value and state significance
- T-test: value and p-value and state significance for first variable.
- T-test: value and p-value and state significance for second variable.
