     These functions provide information about the Laplace distribution
     with location parameter equal to `m' and dispersion equal to `s'. 
     `dlaplace' gives the density, `plaplace' gives the distribution
     function, `hlaplace' gives the hazard function.

     The Laplace distribution has density

                    f(y) = exp(-abs(y-m)/s)/(2*s)

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

_U_s_a_g_e:

     dlaplace(y, m, s)
     plaplace(q, m, s)
     hlaplace(y, m, s)

_A_r_g_u_m_e_n_t_s:

       y: vector of responses.

       q: vector of quantiles.

       m: vector of location parameters.

       s: vector of dispersion parameters.

_S_e_e _A_l_s_o:

     `dexp' for the exponential distribution and `dcauchy' for the
     Cauchy distribution.
