The goal of regression analysis is to describe the relationship between two variables based on observed data and to predict the value of the dependent variable based on the value of the independent variable.igure 1 â Obtaining predicted values for data in Example 1. Figure 1 â Obtaining predicted values for data in Example 1. The predicted values can be obtained using the fact that for any i, the point (xi, Å· i) lies on the regression line and so Å· i = a + bxi.
