Hi,
I have 1000 observations for 6 different products. Each product is rated on a scale of 1 to 10 on 12 attributes. I want to have a perceptual map for each product with respect to attributes. The problem is I think correspondence analysis can only be used with frequency data, and not with this type of data. If we can transform this scale some how...

Thanks

I'm sorry, but these questions are too complex to be addressed on here, questions like this should be addressed to your supervisory team who have access to your data.

Or some universities have some kind of statistics support service to help students with questions like this.
