Hi there. I would like to ask you one question about variance of estimator.(adsbygoogle = window.adsbygoogle || []).push({});

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. Im not sure if it's correct, but i got that its equal to n*β. But how about variance.

Any help would be appreciated!
