   alpha: Array of length `p' containing AR coefficients
          $lpha$.

    rvar: Real scalar containing error variance
          $sigma^2(>0)$.

       n: If `ARSPPEAK' is being used for estimation pur-
          poses, {`n'} is an integer containing the length
          of the realization that was used to estimate the
          parameters of the process.  If the parameters are
          the true values, let ${`n'}=1$.

   start: An optional argument that is a real scalar con-
          taining a starting value $(0<{t{start}}<.5)$ for
          the maximum finding procedure.
