Define Kurtosis For Dummies. Normally distributed data establish the baseline for kurtosis. In Matlab the function kurtosis kurt in the EEGLAB toolbox.
Fat-tailed is sometimes also defined as a subset of heavy-tailed. A kurtosis value of 0 indicates that the data follow the normal distribution perfectly. Kurtosis is defined as the fourth moment around the mean or equal to.
Sample questions What does the standard deviation measure.
A kurtosis value of 0 indicates that the data follow the normal distribution perfectly. Kurtosis in the Matlab statistical toolbox gives an indication of the gaussianity of a distribution but the fixed-point ICA algorithm uses a slightly different measure called negentropy. Solve the following problems about standard deviation and variance. The 3 comes into the picture because thats the kurtosis of something special called the standard normal distribution.
