The impact of weighting methods on properties of RIED balance series

Abstract

The article examines the impact of weighting methods on the properties of balance series obtained on the basis of business tendency surveys, conducted by RIED WSE. We analyzed all variables with three available variants of answers which are tested in the RIED survey regularly every month. For each variable, both state and expectations were studied. We analyzed, among others, descriptive statistics, turning points and stationarity of the obtained by different methods series. The conclusions that could be drawn from the analysis of balance series obtained with the use of different methods coincide. The analysis that has been carried out with the use of a broad set of variables allows to conclude that despite the arbitrary weights used, series provided by RIED WSE are adequate.
