Promax: Promax Factor Rotation (GPArotation format)
Description Usage Arguments Value References
Description
This implements the promax rotation with output consistent with the naming conventions of the GPArotation package. Promax rotation is a factor rotation method which seeks a solution that is as orthogonal as possible, but allows obliqueness rather than forcing an orthogonal solution.
Usage
1 | Promax(L, m = 4)
|
Arguments
L |
A factor loading matrix |
m |
The power used for promax. Values of 2 to 6 are recommended. Defaults to 4. |
Value
A list (which includes elements used by facanal) with:
- loadings
The new loadings obtained by L %*% Th.
- Th
The rotation matrix.
- method
A string indicating the rotation objective function.
- orthogonal
A logical indicating if the rotation is orthogonal. Is FALSE for Promax.
- Phi
t(Th) %*% Th. The covariance matrix of the rotated factors.
