	^fitpower^ lhsvar rhsvar [^,^ graph_options]


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

^fitpower^ fits and graphs a power curve of the form Y=aX^^b, where ^^b is an
exponent, and a and b are regression coefficients.  It calculates the adjusted
R-squared of the fit of the non-linear regression to the data, and displays it,
the regression equation, and the significance level on the graph.


Example
-------

 . ^fitpower weight length, saving(jt1)^

graphs weight against length as a power curve, and saves the graph into a file
for printing with gphdot or gphpen.
