Methods

get_coordinates	Returns random coordinates for visualisation purposes.
get_covariance_matrix	Returns the covariance matrix.
get_mean_vector	Returns a vector containing the mean value of each asset.
get_period_return_covariance_matrix	Returns a vector containing the mean value of each asset.
get_period_return_mean_vector	Returns a vector containing the mean value of each asset.
get_similarity_matrix	Returns time-series similarity matrix computed using dynamic time warping.
run	Loads data, thus enabling get_similarity_matrix and get_covariance_matrix methods in the base class.
