Jindrová, Věra ; Sekničková, Jana (advisor) ; Školuda, Václav (referee)
The bachelor thesis aims to create a comprehensible user's manual for econometric software GRETL in the Czech language. It begins with the introduction of software GRETL and then acquaints the reader with a range of possible uses of the software when working with data. Thesis briefly describes the main characteristics of the possible linear regression model, such as multicollinearity, autocorrelation and heteroscedasticity, including possible testing in the particular software and evaluation of specific tests. The key part deals with defining and specifying data for their subsequent analysis in the software, compilation of a model, estimates of parameters of an econometric model using the least squares method, the weighted least squares method and the generalized least squares method. Furthermore, the thesis deals with hypotheses testing and confidence interval estimations, and also shows how to create and edit graphs in GRETL and explains each menu item in detail. All steps are supported by a graphical supplement and specific examples.
