Logarithmic-Normal Model of Income Distribution in the Czech Republic

Abstract

While making a statistical model the main task is both, to find out a theoretical distribution function that would characterize empirical frequency distribution and to choose suitable methods to calculate parameters of the model. As a theoretical model of income distribution, logarithmic-normal distribution has been used so far. Recently used type of theoretical model was derived from the character of a particular feature and from a longtime experience with its behavior before revolution. One of the important tasks of the present time is to make statistical analysis of impact of economic changes on distribution of annual financial income per household, or per person after velvet revolution. This paper concentrates on verification of validity of the statistical model of income distribution in the Czech Republic that has been used so far. It also covers a suitable estimate of model’s parameters.
