What are the libraries for statistical analysis (calculation of the coefficient of kurtosis, asymmetry) for java?

Question

Java

There is a task:
Analysis of the data array, which is a spectrogram.
A library is needed to calculate such parameters.
PS Or if it's not difficult, tell me the name of this analysis in English.
Update: As I thought, the problem is ignorance of the materiel.
These coefficients are calculated by integrating a smooth function.
