      subroutine daisy(nn,jpp,x,valmd,jtmd,jdat,vtype,ndyst,mdata,disv)
c     c
c     c  Calculating dissimilarities between objects or variables
c     c

      integer nn, jpp
c     c          nn  = number of objects
c     c          jpp = number of variables used for the calculations

c     c  The following vectors and matrices must be dimensioned in the
c     c  main program :
      double precision x(nn,jpp), valmd(jpp)
      double precision disv(1+nn*(nn-1)/2)
      integer jtmd(jpp), jdat, vtype(jpp), ndyst, mdata

c       vtype was character originally
c       vtype(j) is the type of variable j:
c              = 1 (A) for an Asymmetric binary variable
c              = 2 (S) for a  Symmetric  binary variable
c              = 3 (N) for a  Nominal  variable
c              = 4 (O) for an Ordinal  variable
c              = 5 (I) for an Interval variable (additive)
c              = 6 (T) for a  raTio    variable (log transformed)

c       vector jtmd is only read if there are missing values : if(mdata)
c       jtmd(j) =  0 if variable j is binary
c               = -1 if variable j is not binary and has missing values
c               = +1 if variable j is not binary and has no missing values
c VAR
      double precision clk,dlk, pp,ppa, rpres
      integer j,k,l,la, lsubt, nlk, nbad, npres
      logical hasNA

      hasNA = (mdata .ne. 0)

c         calculation of the dissimilarities
      nlk=0
      if(jdat .eq. 1) then
c Case I: `mixed
