Under the assumption that MLR 1-4 holds for the original model‚ we can substitute in to the regression model to produce equation respond(true)= β(0)+ β(1)resplast+ β(2)avggift+ β(3)propresp+ β(4)mailyear+u+e(0). Given that there are no correlation with the explanatory variables‚ OLS estimators βs will remain constant and unbiased. This is an extension

2008 AACE INTERNATIONAL TRANSACTIONS EST.03 An Introduction to Parametric Estimating Mr. Larry R. Dysert‚ CCC A ACE International describes cost estimating as the “predictive process used to quantify‚ cost‚ and price the resources required by the scope of an asset investment option‚ activity‚ or project [1].” The methods and techniques used to prepare a cost estimate will typically vary based on the level of project definition available at the time the estimate is prepared [2‚ 3].

and the pooled time regression method is used to analyze the data. Return model as well as Price model was used to determine the value relevance of financial statements’ information. It revealed that the value relevance of accounting information under the Price model has more explanatory power than Return Model. The empirical results of the study indicate that Earning Per Share (EPS) is the most value relevant variable in this study and it is significant at 0.01 level. Regression of earnings‚ book
