Analysis on all variables
Should we analyze the correlation- or the variance-covariance matrix? Why?
Perform statistical tests on the eigenvalues in order to assess the relevant number of components to retain!
Exclude ‘alder’ and ‘vegt’
Repeat the above analyses!
Condition on alder and vegt
Compare the partial correlations and the eigenstructure based on those with the results in B!
Are there big differences?
Explain this by means of adequate statistical analyses.
Partial correlations based on vegt (by hand!)
