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

     Checks the weak, moderate, and strong stochastic transitivity.

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

     strans(M)

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

       M: a square matrix or a data frame consisting of absolute
          frequencies

_D_e_t_a_i_l_s:

     With erroneous data, the number of violations is only a
     descriptive index of the goodness of fit of a model. When the
     sample size is small (or too large), however, the violations might
     be the only reliable index for the model selection.

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

     A table displaying the number of violations of the weak, moderate,
     and strong stochastic transitivity, the number of tests, the error
     ratio (violations/tests), and the mean and maximum deviation. 

     pcm: the square matrix of relative choice frequencies

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

     'OptiPt'.

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

     data(rugr)  # absolute choice frequencies
     strans(rugr)  # report of the transitivity violations
     strans(rugr)$pcm  # relative frequencies
