  • Why would one eigenvalue correspond to multiple eigenvectors?
    The converse statement, that an eigenvector can have more than one eigenvalue, is not true, which you can see from the definition of an eigenvector However, there's nothing in the definition that stops us having multiple eigenvectors with the same eigenvalue
  • Why eigenvalues are greater than 1 in factor analysis?
    Using eigenvalues > 1 is only one indication of how many factors to retain Other reasons include the scree test, getting a reasonable proportion of variance explained and (most importantly) substantive sense
  • Eigenvalues and eigenvectors - Wikipedia
    Because of the definition of eigenvalues and eigenvectors, an eigenvalue's geometric multiplicity must be at least one, that is, each eigenvalue has at least one associated eigenvector Furthermore, an eigenvalue's geometric multiplicity cannot exceed its algebraic multiplicity
  • Chapter 6 Eigenvalues and Eigenvectors - MIT Mathematics
    The eigenvalues are the growth factors in Anx = λnx If all |λi|< 1 then Anwill eventually approach zero If any |λi|> 1 then Aneventually grows If λ = 1 then Anx never changes (a steady state) For the economy of a country or a company or a family, the size of λ is a critical number
  • 4. 2: Properties of Eigenvalues and Eigenvectors
    In our example, we found that the eigenvalues of \(A\) are \(-6\) and \(12\); the eigenvalues of \(A^{-1}\) are \(-1 6\) and \(1 12\) Also, the eigenvalues of \(B\) are \(-1\) , \(2\) and \(3\), whereas the eigenvalues of \(B^{-1}\) are \(-1\) , \(1 2\) and \(1 3\)
  • Eigenvectors and eigenvalues - 3Blue1Brown
    It's also possible to have just one eigenvalue with more than just a line full of eigenvectors A simple example is the matrix which scales everything by 2 2 2 The only eigenvalue is 2 2 2, but every vector in the plane gets to be an eigenvector with that eigenvalue
  • How can I justify that an initial eigenvalue larger than 1 . . .
    EFA showed that the first six initial eigenvalues were more than 1, so I needed to retain them according to Larsen Warne (2010) and Shrestha (2021) stated that researchers retain all
