| Quantlet: | factorrot | |
| Description: | performs a rotation of factors from factor analysis |
| Usage: | rotated = factorrot(loadings{,labels}) | |
| Input: | ||
| loadings | p x k matrix which contains the factor loadings in columns | |
| labels | optional p x 1 string vector containing labels of p variables, default: numbers of order of the variables | |
| Output: | ||
| rotated | p x k matrix of last rotated loadings | |
