WebSimple Linear Regression Analysis Let's look at the two examples. Example 1 : A cost modeller wants to know the cost for a new contract based on the data collected from the previous contracts. We must examine the data collected from previous contracts, in order to make any prediction as to how much a new contract would cost. WebRegression Template The regression template is used in CON 270 and allows the user to enter paired data for dependent and independent variables to perform least squares best fit simple linear regression for purposes of developing cost estimating relationships in contract pricing.
