Skewness-Kurtosis ratio of the return distribution
Skewness-Kurtosis ratio is the division of Skewness by Kurtosis.
SkewnessKurtosisRatio(R, ...)
R |
an xts, vector, matrix, data frame, timeSeries or zoo object of asset returns |
... |
any other passthru parameters |
It is used in conjunction with the Sharpe ratio to rank portfolios. The higher the rate the better.
SkewnessKurtosisRatio(R, MAR) = S/K
where S is the skewness and K is the Kurtosis
