Abstract

In this paper we consider two methods for estimating parameters in the linear model. First approach is the classical regression model where it is assumed that independent variable is deterministic. In the second one we assume that both independent as well as dependent variables are randomly distributed values related with each other by linear relationship and we build the model used for parameters' estimation. For model evaluation we made a comparison of two approaches using data from GUS.
