Golan et al. (1996) proposed an alternative method for the parameters estimation of the regression models; in case of ill-posed problems; as an extension of the entropy measure; introduced by Shannon and as a generalization of the Maximum Entropy Principle (MEP) developed by Jaynes (1957; 1968).
The job satisfaction model is considered as motivating example; for developing a performance comparative study between the GME and PLS regression methods. Both GME and PLS methods are implemented on the job satisfaction model; where several level of correlation are generated among the predictors. For each level of correlation; regression coefficients and diagnostic values are calculated; for showing the performance of both methods in case of ill-posed problems.
The paper is divided in two main sections: The first part consider the introduction of the two estimation methods; in way to give a general overview of both techniques and also the main characteristics.
The second part gives a brief introduction to the job satisfaction model and then starts with the simulation study; comparing both estimation results; giving a discussion in case of multicollinearity problem.
