This article deals with approximation of empirical distribution to standard normal distribution using Johnson transformation. This transformation enables us to approximate wide spectrum of continuous distributions with a normal distribution. The estimation of parameters of transformation...

Statistical computing when input/output is driven by a Graphical User Interface is considered. A proposal is made for automatic control of computational flow to ensure that only strictly required computations are actually carried on. The computational flow is modeled by a directed graph for...

This article describes the trend of income distributions in Czech Republic over the years 1995-2008. There is not social economy study on the topic incomes. We analyze time series of incomes over these years. The income distributions and their trends are analyzed over all Czech Republic, next...
