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

     Computes the Finn coefficient as an index of the interrater
     reliability of quantitative data. Additionally, F-test and
     confidence interval are computed.

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

     finn(ratings, s.levels, model = c("oneway", "twoway"))

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

 ratings: n*m matrix or dataframe, n subjects m raters.

s.levels: the number of different rating categories.

   model: a character string specifying if a '"oneway"' model (default)
          with row effects random, or a '"twoway"' model with column
          and row effects random should be applied. You can specify
          just the initial letter.

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

     Missing data are omitted in a listwise way. 
     The Finn coefficient is especially useful, when variance between
     raters is low (i.e. agreement is high). 
     For the computation it could be specified if only the subjects are
     considered as random effects ('"oneway"' model) or if subjects and
     raters are randomly chosen from a bigger pool of persons
     ('"twoway"' model).

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

     A list with class '"irrlist"' containing the following components: 

 $method: a character string describing the method applied for the
          computation of interrater reliability.

$subjects: the number of subjects examined.

 $raters: the number of raters.

$irr.name: a character string specifying the name of the coefficient.

  $value: coefficient of interrater reliability.

$stat.name: a character string specifying the name and the df of the
          corresponding F-statistic.

$statistic: the value of the test statistic.

$p.value: the p-value for the test.
