Astudent fitted a linear regression function for a class assignment. the student plotted the residuals e (sub i) against y (sub i), and found a positive relation. when the residuals were plotted against the fitted values y hat (sub i), the student found no relation. how could this difference arise? which is the more meaningful plot?

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
