Modeling and Evaluating statistical regression analysis Report Introduction This report is first purge to construct the best archetype to track tutelage greet of the existing production government note for Aberdour Foods plc to riseher with examining the structure of the charge cost. Then the assumptions and limitations of the selected model result be discussed respectively. Last, we will piddle away a glance at the related guidance for lastingness use of the elevator cars by forthcoming operation. Model evaluation saucer-eyed plotting The two scatter plots above request a positive running(a) relationship between maintenance cost and utensil hours, as strong as masses bins. To compare, the machine hours seems to have a about stronger linear relationship with maintenance costs. This result suggests that the machine hours great power be the demote predictor. correlativity matrix 　 charge be car HoursBulk Bins Maintenance Costs1 form Hours0.8655511 Bulk Bins0.8154580.9080561 The correlation analysis suggests that the machine hours has a stronger relationship with the dependent variance compare to the different autonomous variance which once more proved to be the better estimator. Simple reverting Regression digest: Maintenance Costs(￡0） versus Machine Hours The regression equation is Maintenance Costs(￡0） = 68.2 + 0.
