Originální abstrakt

The paper deals with identification of significance level for testing the time-frequency transform of the data. The usual procedure of time-frequency significance testing is based on the knowledge of background spectrum. Very often we have expectation of the background noise character (Gaussian noise, Red noise, etc.). Our paper deals with the case when character of the noise is unknown and may not be Gaussian despite our assumptions. Thus, we propose how to identify own critical values for testing time-frequency transform significance with respect to the data character. We compare our knowledge to critical quantile of chi-square distribution.
