Normal distribution and skewed distribution
WebIn probability theory and statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. The skewness … Webbution can be highly skewed as well as symmetric. If −1 < λ < 0, then the distribution is negatively skewed. If 0 < λ < 1, then the distribution is positively skewed. If λ = 0, then the distribution is symmetric. Finally, p and q control the kurtosis of the distribution. As p and q get smaller, the kurtosis increases (i.e. becomes more ...
