Webby = skewness(X,flag) specifies whether to correct for bias (flag = 0) or not (flag = 1, the default).When X represents a sample from a population, the skewness of X is biased, meaning it tends to differ from the population skewness by a systematic amount based on the sample size. You can set flag to 0 to correct for this systematic bias.
