Method Detail

getMean

Matrix getMean()

This method returns the first central moment, i.e. the mean vector, of the random variable.

Returns:

a Matrix instance

getVariance

Matrix getVariance()

This method returns the second central moment, i.e. the variance-covariance matrix, of the random variable.

Returns:

a Number instance
