Kurtosis, defined as the fourth moment value of signal, shows the peakedness of probability distribution graph.
Positive value means that the shape of probability distribution graph is more peaked than normal distribution, while negative value means flatter shape.By use of the kurtosis analysis method you can analyze the kurtosis of each channel from the data and have it displayed on a display window. This case is to analyze the kurtosis for the whole data. On the other hand, if you wish to analyze the kurtosis changing with time, you can use the moving window analysis together. Select the target data from the analysis window first and then click Moving Window analysis icon in the analysis tool bar. And a window setting dialog box as shown below will pop up. In this dialog box, you can configure the window value and the overlap ratio of your choice; the former means the range of the data, while the latter represents the degree of overlap among the data. The window value and the overlap ratio are explained in the analysis method of Moving Window in detail. Please refer to it!
