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

     The function performs 50-50 MANOVA testing based on a matrix of
     hypothesis observations and a matrix of error observations.

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

     ffmanovatest(modelData, errorData, stand = 0, part = c(0.9, 0.5),
                  partBufDim = 0.5, minBufDim = 0, maxBufDim = 1e+08,
                  minErrDf = 3, cp = -1)

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

modelData: matrix of hypothesis observations 

errorData: matrix of error observations

   stand: Standardisation (0 or 1) of responses 

    part: The variance explained required when choosing the number of
          components for testing. The default value is 0.5, but to
          choose a single component 0.9 is required.  

partBufDim: tuning parameter for the number of buffer components

minBufDim: minimum (if possible) number of buffer components

maxBufDim: maximum number of buffer components

minErrDf: minimum number of "free dimensions"

      cp: correction parameter when "few" responses

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

     'modelData' and 'errorObs' correspond to 'hypObs' and 'errorObs'
     calculated by 'xy_Obj'.

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

     A list with components 

  exVar1: variance explained by 'dimY' components

  exVar2: variance explained by 'dimY+bufferDim' components

     dim: dimension of final "MANOVA-space"

    dimX: the ordinary degrees of freedom for the test

    dimY: number of components for testing

bufferDim: number of buffer components

       D: test statistic: Wilks' Lambda

       E: test statistic: Roy's Largest Root

       A: test statistic: Hotelling-Lawley Trace Statistic

       M: test statistic: Pillay-Bartlett Trace Statistic

      pD: p-value: Wilks' Lambda

      pE: p-value: LOWER BOUND for Roy's Largest Root

      pA: p-value: Hotelling-Lawley Trace Statistic

      pM: p-value: Pillay-Bartlett Trace Statistic
