| PROMAX | Perform Promax oblique rotation after orthogonal Varimax rotation of the rows of the input data. A method for linear decomposition by "rotating to simple structure." |
| Usage: | >> [R] = promax(data,ncomps); >> [R,V] = promax(data,ncomps,maxit); |
| Inputs: | |
data |
Promax operates on rows of the input data matrix |
ncomps |
operate on the N largest PCA components (default|0 -> all) |
maxit |
maximum number of iterations {default|0 -> 5} |
| Outputs: | |
R |
is the non-orthogonal Promax rotation matrix i.e., >> promax_rotated_data = R*data; |
V |
is the orthogonal Varimax rotation matrix i.e., >> varimax_rotated_data = V*data; |
