Econometrics 
Which one is correct about the tradeoff between bias and variance? Check all that apply. We should always avoid bias, even if there is a big variance. If the variance is very inflated, we prefer to accept a small bias to avoid inflated variance. If two variables are highly correlated, the inflation in variance will be negligible. If the two variables are absolutely uncorrelated, we have neither bias problem nor inflated variance problem.
