Improving a Multifactor Forecasting Model for Future Changes in Management Efficiency in the Services Sector

The article presents directions for improving the multifactor model of forecasting future changes in the management efficiency of the service sector. Three limitations of existing models are identified - the subjectivity of the selection of factors, the accumulation of error in the forecast of factors, and their incompatibility with structural changes. As a result of the research, a procedure for selecting factors on a statistical basis, a mechanism for reducing the accumulation of errors, a model with adaptive coefficients, and an integral specification of the improved model are proposed. A system of complex criteria for assessing the quality of the model is developed.
