INTERDEPENDENCE OF PARAMETERS IN SPECTROSCOPIC DATA REDUCTION

In order to overcome the lack of sufficient information and of practical meaning resulting from the use of correlation coefficients, a new measure of the interdependence of the physical parameters in a statistical fitting to data, the Freedom, is proposed. This quantity is easily computed using the correlation matrix, and it provides an idea of the dependence of each parameter on all the others, based on a clear definition. Its use can be generalized to the case of nonlinear dependences. © 1990.
