Similarity Analysis of Growth Cycles

Warianty tytułu
Języki publikacji
This paper introduces the definition of similarity measure of two functions. This measure is a quantitative characteristic of similarity of functions and it can be helpful in comparison of the sets of qualitative and quantitative data on economic activity. The measure includes two special cases: functions defined on intervals and functions with discrete domains. Similarity measure admits many generalisations, e.g. it can be extended on the space of stochastic processes. This fact allows testing several hypotheses about mutual properties of time series. These measures are then applied to analyse the similarity between the actual dynamics of the aggregate economic activity in Poland and its representation by survey data. (fragment of text)
