  36 *The analysis is based on a Burt's table:
  37 *
  38 */BURT-DATA FINLAND / this creates the Burt's table from the data
  39 */MATSHOW BURT.M / Burt's table as a matrix file
  40 *A suitable data file for Multiple Correspondence Analysis is created by
  41 */BURT-MCORRESP MCAFIN,BURT.M,CLASS.M 
  42 *FILE SHOW MCAFIN / New data file
  43 *FILE ACT  MCAFIN / Activate supplementary classes with `S'
  44 */MCORRESP MCAFIN / Multiple Correspondence Analysis
  45 *
  46 *The /MCORRESP sucro computes the numerical results by employing the
  47 *CORRESP operation of Survo. In addition, it gives a ready made work
  48 *scheme (a whole edit field), where parameters can be modified and the
  49 *graphs re-produced and saved in Windows metafiles or PostScript files.
  50 *    The above picture is created by slightly modifying the work scheme
  51 *given by the sucro. The PLOT commands needed are very simple, as the
  52 *data file was specially prepared for this task earlier, by the
  53 */BURT-MCORRESP sucro.
