     These functions provide information about the Burr distribution
     with location parameter equal to `m', dispersion equal to `s', and
     family parameter equal to `f'. `dburr' gives the density, `pburr'
     gives the distribution function, `hburr' gives the hazard
     function.

     The Burr distribution has density

            f(y) = s (y/m)^(s-1)/(m^s (1+(y/m)^s/f)^(f+1))

     where m is the location parameter of the distribution, s is the
     dispersion, and f is the family parameter.
