By default, the Linear Weights graph displays the relative magnitudes of the T-statistic associated with each coefficient in the linear regression model:

- Select the Graphics Options tab.
- Change the Graph Type to Standardized Coefficient to view the standardized coefficient values.
Although not generated automatically, a Scatter Plot is useful for analyzing the model built with the Linear Regression analysis. As an example, a scatter plot is brought up to look at the dependent variable (“cc_rev”), with the first two independent variables that made it into the model (“avg_cc_bal,” “income”). Create a new Scatter Plot analysis, and pick these three variables in the Selected Tables and Columns option. The results are shown first in two dimensions (avg_cc_bal and cc_rev), and then with all three:
