 Input:



  fadata                 name of active data (I x J matrix) file, Obligatory Parameter 

                         

  fsldata                name of supplementary row data (K x J matrix) file 

                         

  fscdata                name of supplementary column data (I x Q matrix) file 

                         

  titl                   title of data set (text string) 

                         

  fal                    name of row label (I x 1 string vector) file 

                         

  fac                    name of column label (J x 1 string vector) file 

                         

  fsl                    name of supplementary row label (K x 1 string vector) file 

                         

  fsc                    name of supplementary column label (Q x 1 string vector) file 

                         

  outdoc                 name of output file, default = "out.txt" that consists of Eigenvalues 

                         corresponding to the principal axes, Coordinates of items on the principal axes, 

                         Contributions of active items relative to a principal axis, 

                         Squared correlations which indicate the part of the variance of 

                         a variable explained by a principal axis, Relative weights 

                         (marginal frequencies) and Distances of items to the origin. 

                         

 Output:



                         - see above file "outdoc" 

                         - some graphs are obtainable by interactive requests. 

                         The graphs represent the configurations of items 

                         in projection planes formed by the first principal 

                         axes taken two at a time. They 

                         help to interpret the relations between items. 

                         Active row labels are written in blue, 

                         Active column labels are written in green, 

                         Supplementary row labels are in red 

                         Supplementary column labels are in magenta.
