The
buttons at the top of the worksheet perform various actions.
The *Change* button brings up a dialog box that allows
a new number of states. The several arrays on the worksheet
are expanded or contracted to accommodate the new state number.
Data currently entered in the matrix remain so that an expanded
or contracted problem can easily be entered.
The *Calculate* button
computes row and column sums and reports if the matrix entries
do not define an acceptable Markov Chain transition matrix.
The *Analyze* button divides the states into recurrent,
transient, or absorbing classes. The example has only one
class of recurrent states. When the model is changed by adding
or deleting states or changing transition probabilities,
it is necessary to click on the *Analyze* button. The
analyze activity automatically updates arrays on related
worksheets.
The buttons along the left
side of the worksheet construct new worksheets to perform
the analyses indicated. |
