To calculate a residual for the ith observation, we do not need the:
|
Actual value of Yi. |
|
|
Estimated intercept. |
|
|
Estimated slope. |
|
|
Standard error. |
Homework Answers
Estimated value of Yi = Estimated intercept + Estimated slope * Xi
Residual for the ith observation = Actual value of Yi - Estimated value of Yi
= Actual value of Yi - (Estimated intercept + Estimated slope * Xi)
From above equation, we need Actual value of Yi, Estimated intercept and Estimated slope to calculate a residual for the ith observation.
So, we do not need Standard error for the calculation.
The answer is Standard error.

(e) Let Wi denote the random response for the ith observation and denote the associated random error. Suppose the constant variance assumption has been violated such that Var(e) is proportional to (y) = H . That is, Var(€;) = Var(yi) = Chw where c is some constant. Consider a transformed response variable, g(x). We can write the first-order Taylor expansion of g() at Hy, as 9(y) (y) + (y) (yi - My), (1) where g'( ) is the first derivative...
