The high median is always a member of the data set. When the number of data points is odd, the middle value is returned. When it is even, the larger of the two middle values is returned. >>> WebThe algorithm first computes high-order statistics from the data. It resorts to using a TI, only if enough replicates could not be identified to determine the conditional probabilities. A shortcoming of the method is related to selecting the spatial cumulants. chime it conference
