Hi there. I would like to ask you one question about variance of estimator.
Suppose that [itex]Y_i=βX_i+ε_i[/itex] and β estimator is [itex]\bar{Y}[/itex] / [itex]\bar{X}[/itex].
I calculated mean of estimator. I am not sure if it's correct, but i got that its equal to n*β. But how about variance.
Any help would be appreciated!
