	^fpshow^ [^,^ ^mod^el^(^#^)^ ^b^est ^i^nfo ^mon^otonic ^d^evdiff^(^#^)^ ]


Description
-----------

^fpshow^ gives extra information on the regression models fitted by ^fp^.  This
information includes a comparison of the deviance of the best-fitting model 
with the deviance of each of the other models and an indication if each FP
function is monotonic (when that can be determined).


Options
-------

^model(^#^)^ displays results from model number ^#^ and makes that model the current
    model.

^best^ displays results from the best-fitting model and makes that model the
    current model.

^info^ displays the following information about each model fitted: the model
    number; the powers used in the FP; whether the FP is monotonic; the
    deviance; and the increase in deviance over the best-fitting model.
    Monotonicity cannot easily be determined when the degree of the model is
    greater than 2.  In these cases, the monotonicity is displayed as ^--^.

^monotonic^ displays only models known to be monotonic.

^devdiff(#)^ displays results only for the worst-fitting models, that is, those
    whose deviance is at least ^#^ greater than that of the best-fitting
    model.  If ^#^ is negative, only the best-fitting models are displayed,
    those whose deviance is no more than |^#^| greater than that of the
    best-fitting model.  A sensible value of |^#^| is 4.
