Covariance matrix input

[juliuspfadt]

• cov matrix input for PCA and EFA (fixes [Feature Request]: Use correlation matrix as input jasp-issues#1802)
• and for CFA

[FBartos]

• 
  (I assume a different message should be there? :)

• 
  (this could have an upper bound based on the number of selected variables?)

• 
  (similar here?)

• [ ]
  
  (not sure about this one)

• [ ]
  
  (also with some other methods)

I changed the code to have a better check, this is all mostly related to loading a data matrix instead of a covariance matrix. You mind checking with a cov matrix?

[juliuspfadt]

I think the message with the eigenvalue is a bit tricky...
fixed it

[FBartos]

I think the error message is a bit too much on an empty selection :)

also, I get it even if I put my dataset in (which is a cov matrix computed in R:
test_cormat.csv

copilot says it's good to go
