PPT-REGRESSION ANALYSIS AND ORDINARY LEAST SQUARES (OLS)

A statistical process for estimating the relationships among variables REGRESSION ANALYSIS Functional Relationship Deterministic An exact relationship between the predictor  X  and the response . Di64256erentiating 8706S 8706f Setting the partial derivatives to 0 produces estimating equations for the regression coe64259cients Because these equations are in general nonlinear they require solution by numerical optimization As in a linear model Session . 3 . – .
