Multiple Choice

To determine the intercept and slope coefficient in a simple linear regression line of Y on X, all the following conditions will be used except for what?

A) $\frac { \sum _ { i = 1 } ^ { N } \left( Y _ { i } - b - m X _ { i } \right) } { N }$ = 0
B) $\frac { \sum _ { i = 1 } ^ { N } \left( Y _ { i } - b - m X _ { i } \right) X _ { i } } { N }$ = 0
C) $\frac{\sum_{i=1}^{N}\left(Y_{i}-m X_{i}\right) X_{i}}{N}$ = 0
D) $\frac { \sum _ { i = 1 } ^ { N } e _ { i } } { N }$ = 0
