- Factor Rotation
- If
is a
solution to the FA equation then
is also a
solution where
is an orthognal matrix
- This multiplication by an orthognal matrix is known as
factor rotation and is performed when the initial
solution does not help in interpretation of results
- Some researchers are trying to interpret results
obtained by an non-orthognal transformation i.e.
is not
orthognal
- Caveats
- If the original variables are already uncorrelated,
there is little reason to perform FA
- Non-unique solutions obtained by performing FA
- Lot of subjectivity involved
