Which of the following is not a limitation of linear regression analysis? A Linear regression analysis assumes that there will be no changes in past performance in the future (for example, efficiency will not improve). B Linear regression analysis can only be used to predict performance that is within the range of data used to develop the regression equation. C Linear regression analysis assumes the relationship between the dependent variable and independent variable is linear. D Regression analysis cannot be used when it is difficult to accurately measure the impact of efficiency improvements.
