Program Files for Bootstrap-procedure in Excel

(documentation in Dutch)

Program for SIMPLIMAX Oblique simple structure rotation

This program can be downloaded here: file: Simplimax.exe (use right mouse click, and 'save target as' command).
A description of the program can be found here: Simplimax.doc.
The program is a PASCAL based executable program (written for MS-DOS)
Main reference: Kiers, H.A.L. (1994). SIMPLIMAX: Oblique rotation to an optimal target with simple structure. Psychometrika, 59, 567-579.

Program Files for Greatest Lower Bound and MRFA: Minimum Rank Factor Analysis

This program is a PASCAL based executable program (written for MS-DOS).
For Minimum Rank Factor Analysis a windows based program, FACTOR, is available at here
For computing the Greatest Lower Bound (GLB), MRFA can be used specifying 0 components.
In the current implementation of FACTOR this is not possible, so for computing the GLB, one may still use
the mrfa program available here: file: MRFA2.exe (use right mouse click, and 'save target as' command).
A description of the method mrfa can be found here: mrfa.doc.
An example data file can be found here: lord.dat.

Matlab program files for several applications

Three-mode component analysis (Tucker3): Threeway m-files.zip (use right mouse click, and 'save target as' command)
Use: unzip zipped file; run "tucker3.m"
Main reference: Kiers, H.A.L., & van Mechelen, I. (2001).Three-way component analysis: Principles and illustrative application. Psychological Methods, 6 , 84-110.

INDCLUS (Individual Differences Cluster Analysis: indclus.zip (use right mouse click, and 'save target as' command)
Use: unzip zipped file; run "indclus.m"; documention in Word file indclus.doc
Main reference: Kiers, H.A.L. (1997). A modification of the SINDCLUS algorithm for fitting the ADCLUS and INDCLUS models. Journal of Classification, 14, 297-310.

Multi Trait Multi Method Componenent Analysis : mtmm-ca.zip (use right mouse click, and 'save target as' command)
Use: unzip zipped file; run "mtmm.m"; program is interactive; description of method can be found in article, also in zip-file
Main reference: Kiers, H.A.L., Takane, Y., & Ten Berge, J.M.F. (1996) The analysis of Multitrait-Multimethod matrices via constrained components analysis. Psychometrika, 61, 601-628.

Orthogonal Congruence Rotation: Orthog Congr Rotation.zip (use right mouse click, and 'save target as' command)
Use: unzip zipped file; run "OrthCongRot.m"; program is interactive; description of method can be found in article, also in zip-file
Main reference: Kiers, H.A.L., & Groenen, P. (1996) A monotonically convergent algorithm for orthogonal congruence rotation.Psychometrika, 61, 375-389.

Zero correlated constrained Parafac: Zero Correlated Parafac.zip (use right mouse click, and 'save target as' command)
Use: unzip zipped file; you will get three matlab script files containing parafac routines; cpfunc.m gives the ordinary Parafac algorithm, and has the zero correlations constraint as an option.
To see how to use this function, first type (in Matlab) "help cpfunc". The m-files Parafac "UncorrColumns Alg 1'.m" and "Parafac UncorrColumns Alg 2'.m" use the two fast algorithms described in the article referred to below. In addition you will find some auxiliary files needed to run these script files.
