Tytuł:: End-of-sample vs. Real-time Data: Perspectives for Analysis of Expectations

Opis:: Data revision is usually defined as an adjustment published after initial value had been announced; it may reflect rectification of errors, availability of new information, introduction of new measurement or aggregation techniques etc. This paper addresses the impact of data revisions on measures of expectations and offers an introduction to empirical analysis of data vintage in testing properties of expectations. It also defines and classifies data revisions and presents a review of literature and databases available for the purposes of real time analysis.

Tytuł:: DATA VINTAGE IN TESTING PROPERTIES OF EXPECTATIONS
Autorzy:: Tomczyk, Emilia
Powiązania:: https://bibliotekanauki.pl/articles/453446.pdf
Data publikacji:: 2015
Wydawca:: Szkoła Główna Gospodarstwa Wiejskiego w Warszawie. Katedra Ekonometrii i Statystyki
Tematy:: end-of-sample (EoS) data
real time (RTV) data
data revisions
quantification procedures
expectations
unbiasedness
orthogonality
Opis:: Results of quantification procedures and properties of expectations series obtained for two data vintages are described. Volume index of production sold in manufacturing is defined for end-of-sample and real time data, and evaluated against expectations expressed in business tendency surveys. Empirical analysis confirms that while there are only minor differences in quantification results with respect to data vintage, properties of expectations time series obtained on their basis do diverge.

Tytuł:: Quantification of expectations for general economic situation on the basis of industrial production index with data revisions
Autorzy:: Tomczyk, Emilia
Powiązania:: https://bibliotekanauki.pl/articles/500423.pdf
Data publikacji:: 2015
Wydawca:: Szkoła Główna Handlowa w Warszawie
Tematy:: end-of-sample (EOS) data
real time (RTV) data
data revisions
survey data
general economic situation
expectations
quantification
regression method
Opis:: Use of appropriate data vintages and taking data revisions into account have only recently became a staple of applied econometric analysis. In this paper, the topic of data vintage in regression quantification procedures is readdressed for survey data on general economic situation. From empirical analysis it follows that quantification of survey data on general economic situation on the basis of industrial production index does not present a significant improvement over the use of response balance. Additionally, results obtained for real-time and end-of-sample data are very similar and do not suggest superiority of any of these two data vintages as far as quantification of survey data on general economic situation is concerned
