Mnxn is a non-negative real square matrix subject to a statistical condition,
∑Mi,j =1 for all lines i,
or ∑Mi,j =1 for all columns j,
Compared to the double statistical transition matrix B, its uses are limited to a few events such as:
* Predict the number of defective parts in the assembly line,
**Predict what percentage of a company's accounts receivable will become bad debt.
..etc..
While the double statistical transition matrix B can be used for almost all physical and mathematical events.
