Hello to everyone , i'm new in this forum , i would like to know if there is a relationship between the coefficient and the std in the calculation of the technical efficiency .
I hope i was clear in the explanation of the problem.
Thanks for the Help

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.
