We deal with the models and statistical analysis of the heterogeneity factors influencing both the intensity of increments and their magnitudes. We propose the estimates of these heterogeneities and we evaluate corresponding probability distributions. An application dealing with the process of financial transactions is solved. cav_un_auth*0212937 Mathematical Methods in Economics 2002 /20./ Ostrava CZ 03.09.2002-05.09.2002 BB SI http://hdl.handle.net/11104/0130963 UTIA-B 20020090 2002 2002 Ostrava Technical University 80-248-0153-1 Proceedings of the 20th International Conference Mathematical Methods in Economics 2002 265 271 Ramík J. 340
