Mean-deviation plots

S.Mustonen (2004)

Edit field:

   1 *
   2 *Mean-deviation plots are often used for studying results of
   3 *attitude surveys. A suitable PLOT scheme for such graphs is created
   4 *by a sucro command
   5 *
   6 */DEVPLOT <data>,<type> 
   7 *
   8 *where <type> is either VBAR or HBAR. The user may enhance the
   9 *scheme afterwards according to his/her own requirements.
  10 *
  11 *The data of 20 variables and 300 observations from an attitude survey
  12 *have been generated at random by an |EXAMPLE| sucro, which demonstrates
  13 *how to make typical mean-deviation plots.

  19 *Making the mean-deviation graph by the /DEVPLOT sucro:
  20 */DEVPLOT ATTITUDE,VBAR 
  21 *MINSTAT ATTITUDE / saves basic statistics in matrix file STAT.M .
  22 *FILE DEL _STATM
  23 *FILE SAVE MAT STAT.M TO _STATM / basic statistics to a data file.
  24 *up=mean+stddev down=mean-stddev
  25 *VAR up,down TO _STATM / computes variables according to above formulas.
  26 *
  27 *'up' and 'down' variables may be computed also by other formulas.
  28 *
  29 *PLOT _STATM / TYPE=VBAR VARS=CASE,mean SHADING=2 YSCALE=0(1)5
  30 *DEV=[RED],down,up        (specifying extra line segments in the graph)
