Subject:      correspondence analysis plots in Spss 8
In-Reply-To:  <v03110701b181ac62e4ed@[194.20.45.72]>

I installed v8 and i didn't look very deep into the books yet, but
have a question a question about the correspondence analysis:
 
Why has the rows and column points plot 2 times the same plot in it?
It looks now like a matrix scatterplot 4 parts of a diagram
and diagonally there is nothing. Only on the off-diagonal parts are
two identical but mirrored plots. I first asked for 2 dimensions and
even then this was the case. When I ask for three dimensions the plot
doens't change. A decent matrix scatterplot should change (i think)
to a 3 by 3 matrix scatterplot.
 
I didn't do anything special, scaling was symmetrical, the two
variabels had 4 and 5 categories. I was only testing Spss 8 (does it
work?).
