High skewness and kurtosis
WebWhile skewness focuses on the overall shape, Kurtosis focuses on the tail shape. Kurtosis is defined as follows: Kurtosis is the fourth standardized central moment, of the random variable of the probability distribution. The formula for Kurtosis is as follows: Formula for population Kurtosis (Image by Author) Kurtosis has the following properties: Webthree leads of high resolution 24-h holter data are extracted and preprocessed using Discrete Wavelet Transform (DWT). Next, a sample to sample sliding window is applied to preprocessed sequence and in each slid, mean value, variance, skewness, and kurtosis of the excerpted segment are super-imposed called MHOM. The MHOM metric is then used as
