WebThis test assumes the variance for each εi ε i is related to the values of X X in the following way: lnσ2 i =γ0+γ1Xi ln σ i 2 = γ 0 + γ 1 X i Hence, a linear regression is assumed between σ2 σ 2 and X X. We can fit the line by squaring the residuals and regressing on X X. The third plot in Example 3.3.1 shows the squared residuals ...
