  #  probability distributions is written out to a file named posterior_prob_plot.png
  #  and the PNG image of the disjoint clusters to a file called cluster_plot.png.

  # SYNTHETIC DATA GENERATION:

  #  The module has been provided with a class method for generating multivariate
  #  data for experimenting with the EM algorithm.  The data generation is controlled
  #  by the contents of a parameter file that is supplied as an argument to the data
  #  generator method.  The priors, the means, and the covariance matrices in the
  #  parameter file must be according to the syntax shown in the `param1.txt' file in
  #  the `examples' directory. It is best to edit a copy of this file for your
  #  synthetic data generation needs.
