     The data set 'penicilliumYES' has 36 rows and 3754 columns. The
     variables are  1st order statistics from multi-spectral images of
     three species of _Penicillium_ fungi:  _Melanoconidium,
     Polonicum,_ and _Venetum_. These are the data used in the
     Clemmemsen et al "Sparse Discriminant Analysis" paper.

_F_o_r_m_a_t:

     This data set contains the following matrices:

     _X A matrix with 36 columns and 3754 rows. The training and test
          data.  The first 12 rows are _P. Melanoconidium_ species,
          rows 13-24 are _P. Polonicum_ species,  and the last 12 rows
          are _P. Venetum_ species. The samples are ordered so that
          each pair of  three is from the same isolate.

     _Y A matrix of dummy variables for the training data.

     _Z Z matrix of probabilities for the subcalsses of the training
          data.

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

     The X matrix is not normalized.
