Multivariate Statistical Analysis Framework as a Tool for Bank Performance Assessment (Pod błędnym tytułem; with wrong title : Study Major Choice – Factor Preference Measurement)

Multidimensional statistical analysis uses techniques of variables selection and aggregation. Numerous economic phenomena belong to the application field of multivariate analysis. Generally all phenomena described by large number of variables may be analyzed within this framework. Those phenomena require descriptive characteristics that bring difficulty of clear understanding and unilateral evaluation. Bank evaluation is one amidst the others that undoubtedly demands multidimensional analysis. Bank as an institution of public trust is evaluated both from outside (client, stockholders, investors) and inside (bank management). This call for better methodology: trans-border reference system might be regarded as one of the interesting proposals.The system employs the approach of MCDM techniques i.e. (multiple criteria decision making) and refers to reference objectives (French: but de reference, German: Referenzziel). Generally speaking trans-border reference system defines certain reference system which can be considered as comparative basis for evaluation and gives the opportunity to formulate definite requirements by the evaluators, the receivers, or the ones who order the evaluation.The bank assessment process is being done in three main steps:Step I - clustering of the measures values reflecting banks (or their branches) functioning indicators.Step II - normalizing the measures values.Step III - construction of the aggregate measure (indicator)
