cokurtosis

Learning objectives: Use sample data to estimate quantiles, including the median. Estimate the mean of two variables and apply the CLT. Estimate the covariance and correlation between two random variables. Explain how coskewness and cokurtosis are related to skewness and kurtosis. Questions...

Learning objectives: Describe the four central moments of a statistical variable or distribution: mean, variance, skewness, and kurtosis. Interpret the skewness and kurtosis of a statistical distribution, and interpret the concepts of coskewness and cokurtosis. Describe and interpret the best...

In analyzing Miller's spreadsheet, I realized his book displays the formulas for co-skew and co-kurtosis incorrectly. There is a thematic confusion between the (unstandardized) cross-central moments versus "skew" and "kurtosis" which are standardized: 3.42 and 3.47 forget to divide by N, so they...
