Cullen and frey graph interpretation

WebCombining the two coefficients, Cullen and Frey [18] used the skewness-kurtosis plot (i.e. Cullen and Frey Graph) to depict the skewness and kurtosis of the commonly-used distributions, as shown in Fig.1. For normal, uniform, exponential and logistic distributions, the values of skewness and kurtosis are unique. WebOr copy & paste this link into an email or IM:
