Promax.only {HDMD} | R Documentation |
Promax.only is an oblique rotation of factor loadings. This function is directly derived from the Promax function in the psych package, but only performs the promax rotation without first specifying a varimax orthogonal rotation. Further specifying the power of the fitting function allows for greater versatility.
Promax.only(x, m = 4, rotate.structure=NULL)
x |
matrix of factor loadings |
m |
power of fitting function |
rotate.structure |
rotation matrix if loadings have been prerotated. Default is the identity matrix. |
An oblique factor rotation will rescale the loadings with factors having correlated structure Phi
loadings |
Oblique factor loadings |
rotmat |
Rotation matrix structure. If rotated.structure supplied, it will be factored into rotmat. |
Phi |
Correlation matrix structure of Factors |
