To view the HMM PDF's, execute the command
This produces the three state PDF plots as shown
in Figure 13.22. The last two arguments
are the indexes of the
two dimensions to be viewed. Since there are
only two dimensions, the only choice is 1,2
(See a description of
software/gmix_view2.m in Section 13.2).
Look at the figure and try to figure out which
PDF corresponds to state 1, 2, and 3.
If a bad starting point was used, it may not
PDF plots of the three state PDF's after convergence.
Aside from some minor outlier modes, the
PDF estimates correctly approximate the
true PDF's. It is easy to see which PDF corresponds to which
state of the simulated HMM.
