Pandas Technical Analysis Pandas TA is an easy to use library that leverages the Pandas library with more than 130 Indicators and Utility functionsMany commonly used indicators are included such as.
Leptokurtic is a statistical distribution where the points along the X-axis are clustered resulting in a higher peak or higher kurtosis than the curvature found in a normal distribution. In addition to using Skewness and Kurtosis you should use the Omnibus K-squared and Jarque-Bera tests to determine whether the amount of departure from normality is statistically significant. This definition of kurtosis can be found in Bock 1975.
Samples from a normal distribution have an expected skewness of 0 and an expected excess kurtosis of 0 which is the same as a kurtosis of 3.
Excess Kurtosis Kurtosis 3. The greater the excess for any investment data set the greater will be its deviation from the mean. X is the mean and n is the sample size as usual. Kurtosis is a statistical measure used to describe the distribution of observed data around the mean.
