MDS/Euclidian distance - How to plot both the cases and the variables in one graph

SOLVED MDS/Euclidian distance-How to plot both the cases and the variables in 1 graph

Hi,

I am using Multidimensional Scaling alscal in SPSS to create a perceptual map with 9 cases, based on 17 attributes. I have figured out how to get a perceptual map based on de Euclidian Distances between the cases and the map shows the cases. However, I also want to plot the attributes in this map, to show which cases are close to which attributes. I have seen in example theses that people did this (I believe also with MDS alscal), but it doesn't make clear how they did this. If anyone can give me a hint on how to do this I would be very grateful!

Thanks in advance!

- Cindy

Hi,

Thanks for your quick reply! I tried Correspondence Analysis in SPSS, but this wasn't an option for my dataset. However, I did figure out (with some old college material) how to plot both cases and variables in one perceptual map. Apparently, instead of computing distances, I had to click on the option that said that my data was rectangular with 9 rows. And that was all :)

uhmmmm...I am curios to know what's the rationale behind that....
Anyway, glad to hear that you sorted the problem out.

Cheers
