The betas are chosen so as to minimize: O Errors O SSR O PMP O Bias O NoiseThe SSR is/are: O All the residuals squared, and then added up O The coefficient of determination O An indicator of bias O The square root of the variance of Y O More than one of the above is trueThe formula for B, is just: O Covariance of x and y over variance of y O Covariance of x and y over variance of x O Covariance of x and y over the standard deviation of x O Covariance of x and y over the standard deviation of y O None of the above is correct
