   AArrgguummeennttss::

    formula: a symbolic describtion for the model to be tested

          g: an integer indicating the number of regressors in
             model under H0

       data: an optional data frame containing the variables in
             the model.  By default the variables are taken
             from the environment which 'reset' is called from

        `reset' performs the Ramsey's RESET-Test on any func-
        tional relation.

   DDeettaaiillss::

        RESET-Test is popular means of diagnostic for correct-
        ness of functional form. The basic assumption is that
        under the alternative, the model can be written by the
        regression eqn{ y = Xbeta + Zmma + u}{y=X * beta + Z *
        gamma} `g' is the number of regressors in `X'. Ramsey's
        RESET is equivalent  to the standard F-Test.  The test
        statistic under H_0 follows a F distribution with df1
        and df2 degree of freedom.

   VVaalluuee::

        A list with class `"htest"' containing the following
        components:

   statistic: the value of the test statistic.

    p.value: the p-value of the test.

     method: a character string indicating what type of test
             was performed.

   data.name: a character string giving the name(s) of the
             data.
