XlR,T:+"N Kurtosisis a measure of whether or not a distribution is heavy-tailed or light-tailed relative to a normal distribution. Consequently if you do try to separate them, you in effect hold yourself unable to assess the effect of increasing skewness to high levels. WebThe values for asymmetry and kurtosis between -2 and +2 are considered acceptable in order to prove normal univariate distribution (George & Positively and Negatively Skewed Defined with Formula A skewness value greater than 1 or less than -1 indicates a highly skewed distribution.
