Hi, Iam trying to create an index using variables capturing various economy related data. In order to reduce the data in groups. I conducted PCA When I conduct KMO after running PCA, the output just states the error "The correlation matrix is singular". Can I still go ahead with the results of PCA? Is KMO a necessary condition for PCA? If yes, how can I fix the singular matrix problem?
Can we go ahead with Principal Components Analysis (PCA) results if KMO result states that correlation matrix is singular?
