Abstract

This paper compares the development of the sample characteristics by the income distribution. Data for this research come from a survey of the Czech Statistical Office Microcensus (2002) and SILC (2005-2009). The studied variable is the annual net household income per capita (in CZK). It was used for the income distribution in Capital Region Prague a model distribution. For purpose of construction of these theoretical distributions has been used three-parametric lognormal curve. Moment method of point estimation of parameters was used in estimating the parameters of the lognormal curve. The paper also deals with the development of probability density curves of income distribution in time. Furthermore, trend analysis was used to study the development of parameters of lognormal curve, on which basis, income distribution predictions were made for next year by region in the Czech Republic. Using the predicted values of the parameters of considered lognormal distribution forecasts of income distributions were constructed for 2010 (interval frequency distribution).
