We have suggested a set of methods for designing mathematical models ofactuarial processes and an algorithm for evaluating unknown parameters with application of the Bayesian approach. The generalized linear models that represent expansion of the linear regression in cases when distribution of random variables differs from the norm are used as mathematical tools. This facilitates a detailed description of the structure and content of the researched model.
Real statistical data on the losses in the car insurance industry and the suggested methods have laid the basis for building a prognostic model of the actuarial process. A model using the Poisson distribution law and exponential function of communication has proved to be suitable for future use. It is confirmed by a minimal error magnitude and reliable estimates of parameters of generalized linear models obtained with the use of the Bayesian approach. We have determined that the normal model with anidentical connection function allows obtaining a result within one iteration with a slight relative errorbut with inaccurate predicted values of losses. Further studies require solution of the following tasks: analyzing and usinga set of risk factors that impact insurance cases, applying methods of intellectual data analysis in modeling, and forecasting actuarial processes.
