APPLICA TION OF THE MIXED ESTIMA TION METHOD IN MODELING THE LOADING VOL UME IN RAIL WA Y TRANSPORT
The article studies the properties of the method of mixed estimation of parameters of regression equations on the example of modeling the volume of loading of the main types of cargo of railway transport of the Russian Federation. The search for the vector of regression parameters using the mixed estimation method is carried out by minimizing the sum of different loss functions for different parts of the sample. The method of splitting the subsample 152 into parts for the method of mixed estimation of the parameters of regression equations is based on the algorithm invented by the authors, based on the estimation of the bias criterion.
