My question is a bit unusual, since it is not about the program itself, but regarding the data.

I have a matrix representing (reverse) distance between each pair of objects. In SEM, we usually work with correlations. A higher correlation represents variables that are closer to each other.

In my experiment, people were asked to classify 45 objects into groups of similar objects. For example, if I have a sample of 1000 people, and 500 put "Banana" and "Apple" in the same group, the (reverse) distance or "closeness" between them will be 500 (in frequency terms) or 0.5 (in probability/proportion).

Eventually, I am left with a matrix of 45X45, where the numbers inside it are the proportion that each pair of objects co-exist in the same group.

In general, I do not see a lot of difference between correlations and proportions (assuming the appropriate transformations), and that's why I thought it can be possible to use this matrix in AMOS. However, I have not found information about this on line or in books.

I would very much appreciate it if someone can refer me to any material that could be of some assistance.

Thank you very much!
