Original abstract
Comparison of irregularly sampled velocity courses represents a problem which is difficult to solve using commercially available statistical software. On that account, novel in-house software CIRDA was developed. In order to compare two samples of data, CIRDA combines usage of kernel regression technique and statistical tests of randomness (tests based on signs of differences, Kendall's rank correlation coefficient test, Spearman's rank correlation coefficient test, turning point test, median test of randomness). The software was applied on velocity data acquired by Phase Doppler Anemometry in a realistic model of human lungs.
Czech abstract
Porovnání rychlostních profilů s nepravidelně rozloženými daty představuje problém, který je těžko řešitelný pomocí komerčně dostupných statistických softwarů. Za tímto účelem byl vytvořen software CIRDA, který kombinuje techniky jádrové regrese a statistické testy náhodnosti (test založený na znaménkách diferencí, na bodech zvratu, na Kendallově a Spearmanově korelačním koeficientu, mediánový test náhodnosti). Software je aplikován na rychlostní profily získané pomocí fázové Dopplerovy anemometrie v realistickém modelu lidských plic.
