This package is in a first draft state.
For determining the number of factors, use ?numfactor at the REPL to see the function documentation, and ?NumFactor to see documentation on the ouput type of the function.
For evaluating observed factors use testobsfactor at the REPL to see the function documenation, and ?ObsFactorTest to see documentation on the output type of the function.
