Table 1 demonstrates the effect of ecg sampling frequency on variation in (average±standard deviation) sampen, of rr interval time series of ten healthy subjects entropy measures of hrv for long term data and medium term data at data length n=1000, 500 found to be more sensitive to ecg sampling frequency. The results have clearly established that modwt based time scale decomposition analysis gives better results than the fourier transform based spectral analysis of bse and nse indexes financial time series. Abstract an attempt is made to understand the pattern of behaviour of the bse sensex by analysing the tick-by-tick sensex data for the years 2006 to 2012 on yearly as well as cumulative basis using principal component analysis (pca) and its nonlinear variant kernel principal component analysis (kpca.

Sample entropy (sampen), refined version of approximate entropy (apen), is a nonlinear complexity measure used to quantify the irregularity of a rr interval time series without biasing an increase in sampen is an indicator of increases in complexity. It provides us with a robust statistical framework for assessing the behaviour of time series, such as asset prices, in order to help us trade off of this behaviour.
