Suppose the variable has been omitted from the following regression equation, is the estimator obtained when is omitted from the equation. If is said to . a. be biased toward zero b. be unbiased c. have a downward bias d. have an upward bias

step-by-step explanation:

what

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.

sorry but i cant draw that
