when predicting an individual outcome what does the mean change mean why do we estimate the mean response and predict individual outcome? why not estimate mean why do we only estimate the mean response why would you estimate the mean response in confidence interval while predicting individual outcome what is the difference between an estimate of the v and an individual prediction? why do we not use the estimate of the mean response in confidence interval predicting individual outcome when can we predict individual outcome why do we use the estimate of the mean response in confidence interval? why would we not use the individual outcome in predicting? why do we not use the estimate of the mean response but predict individual outcomes? why do we estimate a mean response but use a prediction why do we not use the mean response in confidence interval? why do we not use the estimate of the mean response why does our estimation use individual prediction how do you know how much variation is in each prediction why do we use the estimate in confidence interval why do we use the estimate of the mean response in confidence interval but predict individual outcome? what is the source of variability in a prediction explain why we not use mean or estimate
