     _M_G_E_c._2 mean gene expression in cluster 2.

     _M_G_E_c._3 mean gene expression in cluster 3.

     _M_G_E_c._4 mean gene expression in cluster 4.

     _M_G_E_c._5 mean gene expression in cluster 5.

     _M_G_E_c._6 mean gene expression in cluster 6.

     _M_G_E_c._7 mean gene expression in cluster 7.

     _M_G_E_c._8 mean gene expression in cluster 8.

     _M_G_E_c._9 mean gene expression in cluster 9.

_S_o_u_r_c_e:

     Except of 'MGE', the data is published at <URL:
     http://llmpp.nih.gov/lymphoma/data.shtml>. 'MGEc.*' is the mean of
     the gene expression in each of ten clusters derived by
     agglomerative average linkage hierarchical cluster analysis
     (Hothorn et al., 2002).
