If this is homework? Website policy says you need to display some effort, not just repost the question. What part is confusing you. I am not familiar with the technical efficiency term. What class is this problem for.
No , it's not a homework , I know how solve it ( with the error epsilon ) my question was if there is another way to solve the exercise, in particular if there is a relation between the standard and b0 and b1 cols.
