The work deals with the econometric analysis of the prices of mobile phones based on the selected parameters. The aim of this thesis is to determine, which of the selected parameters affect the price of a new mobile phone and how they affects the price. The theoretical part deals at first with the regression model and determining statistically significant variables and significance of the model as a whole. Then I introduce different procedures for finding and selecting the best estimate for the model. In this thesis I will focus on three procedures for the selection of explanatory variables: best subset selection, forward stepwise selection and backward stepwise selection. Finally I mention the detection of multicollinearity and heteroscedasticity testing. In the second part, I apply different procedures for the selection of explanatory variables and afterwards, based on the criteria defined in the first part, I will select the best model. Finally, I compare these models and choose the best one.
