_K_u_r_t_o_s_i_s

_D_e_s_c_r_i_p_t_i_o_n:

     Computes the kurtosis of the values of `x'.

     If N = length(x), then the kurtosis of x is defined as

            N^(-1) var(x)^(-2) sum_i (x_i - mean(x))^4 - 3

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

     kurtosis(x, na.rm=FALSE)

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

       x: a numeric vector containing the values whose kurtosis is to
          be computed.

   na.rm: a logical value indicating whether NA values should be
          stripped before the computation proceeds.

_V_a_l_u_e:

     Returns the kurtosis of x.

_E_x_a_m_p_l_e_s:

     x<-rnorm(100)
     kurtosis(x)
