On the project

The project will focus on research of selected time-frequency analysis methods with economic applications of comovement analysis. The particular focus will be put on sensitivity of methods on sample size and comovement, identification, description of cycle frequency changes in time-frequency domain and optimal fusion of several distinct time-frequency approaches. Recently proposed comovement-selective filter will be extended from wavelet-based method to spectrogram and time-varying autoregressive case and its parameters will be optimized to various comovement measures. The performance of the methods will also be assessed using the Monte-Carlo simulation on the generated data with known properties and the frequency-temporal structure resembling the general properties of the economic indicators. Moreover, proposed approaches will be used in application of frequency-selective regression and the economic interpretation of results will be provided.

Description in Czech
Cílem projektu je formulovat metodu optimální kombinace časově-frekvenčních metod, zobecnit filtr selektivní na společný pohyb, optimalizovat jeho parametry a demonstrovat aplikaci zkoumaných metod do oblasti frekvenčně-selektivní regrese a extrakce parametrů.
