[R] how to calculate　factor Scoring Coefficient s
Dear R users, Recently, I am learning by myself to do factor analysis with R. Could some one guide me how to calculate 'factor scoring coefficients' or obtain 'factor scores' with the results from principal( ) or factor.pa( ) function in psych package? In SAS, it can be done with option SCORE by PROC FACTOR procedure. Many Thanks. felix __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
[R] What is the 'scale' in princomp() function?
Dear R users, When I tried to use princomp() from stats packages to do Principal Components Analysis, I am not very clear what is the scale. And the scores are different from PROC PRINCOMP procedure from SAS. Using the example data from this package: restpc - princomp(USArrests, cor = TRUE) restpc$scale Murder Assault UrbanPop Rape 4.311735 82.500075 14.329285 9.272248 sd(USArrests) Murder Assault UrbanPop Rape 4.355510 83.337661 14.474763 9.366385 Why 'restpc$scale' is different from 'sd(USArrests)'? felix __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
