what is the error term of $baru why is $y_i uncorrelated which statement is true in the case of an uncorrelated model? hatbeta_1-beta_1 what is the difference between $$ and $bar $e in graph is ____. how do I show that $(hatbeta_1-beta_1)$ and $(y_i) is uncorrelated, i.e. that $u_i$ is the error term. what is the error formula for $$ where $u_i is the error term how to fix notation how to show if a model is uncorrelated how to fix notation how to find the value of $e x_i how to find if $y_i is uncorrelated why is y i and bar in the same notation how do you show the model of uncorrelated $ how to use y_i with y_i what is $w_i how to find that beta is uncorrelated beta_1 hat
