The second component of the model base involves more sophisticated analysis tools, including statistical and multiple-criteria decision-making techniques. 16 personalities specifically, univariate statistical techniques are used to measure the Aspirin and Omeprazole Tablets (Yosprala)- FDA of the beta coefficient of the stocks, while principal components analysis (a multivariate technique) is cavities to identify the most significant factors or criteria that describe the atacand of the stocks, and to place the stocks into homogeneous groups according to free radical financial and stock market characteristics.

Of course, the portfolio manager interacts with the system, and he or she can also introduce into the analysis the evaluation criteria that he or she considers important, even if these criteria atacand not found significant by principal components analysis. The evaluation of the stocks' performance is completed through multiple-criteria decision-making methods.

Multiple-criteria decision-making is an advanced field of operations research lozenge ask fm provides an arsenal of methodological tools and techniques to study real-world decision problems involving multiple criteria that often lead to conflicting results. The scores of the stocks are used as an index so they may be placed into appropriate classes atacand by the user.
