Abstracts

W artykule opisano zastosowanie funkcjonalnej analizy składowych głównych PKB. Wykazano użyteczność tej metody w analizach regionalnych. Z obserwacji wynika, że regiony o podobnym poziomie zjawiska wykazywały podobieństwo w utrzymaniu lub zmianie poziomu PKB per capita, a zupełnie inaczej zachowywały się regiony o wyższym PKB per capita, np. podregion stołeczny.

The article describes the use of functional GDP principal components analysis from the exploratory point of view. This analysis is designed to show the variation in the entire sample, not only discrete observations. This is a technique that is often used as an introduction (e.g., dimensionality reduction and data visualization) for further analysis. This approach emphasizes the significant characteristics of associated statistically data sets and provides useful tools for statistical analysis of economic data sets. The study concerns the GDP per capita in Poland. The results showed that the two main functional components explain 98,64% of the variation. This means that the presented visualization and interpretation of the results is reliable. (original abstract)
