RAPIDMINER PCA QUESTION

yunniyunni Member Posts: 3 Learner I

I would like to do a principal component analysis of the taste of ramen.
If I have a score for each noodle(면), the shape (size) of the ramen bowl(그릇), and the taste of the broth(국물), let's perform a PCA analysis with three variables (noodle, bowl, broth).

THIS IS EIGENVECTORS

THIS IS EXAMPLE SET PCA DATA

THIS IS EIGENVALUES

THIS IS READ EXCEL EXAMPLE SET DATA


I tried to draw a graph after getting the PCA, but I'm not sure if the graph is correct.


In addition I don't know what the PCA represents. How can I interpret the graph? Can you help me?

    Thank you for your kind reply. I'll use "weight by PCA" to get the eigen-vector values ​​and challenge the scatter plot matrix! Can I comment if I have any further questions? It really helped me a lot. Thanks
