What is MariMaxCor?

MariMaxCor is a program that performs a hierarchical cluster analysis, according to the algorithm devised by J. Elshout, M. Elshout-Mohr, & P. van de Wijgaart. MariMaxCor is freely downloadable for everyone.

The algorithm used is a modified version of the 'common' cluster analysis. The 'Mari' in MariMaxCor stands for 'marrying', in other words: reciprocity. In this case the reciprocity lies in the correlations between variables in the matrix.
What platforms is MariMaxCor available for?

MariMaxcor is available on the Macintosh only. It is not very likely a MS Windows version will be available.


Download it here for Mac OS X 10.1 through 10.4:

MariMaxCor X 3.5 (*.dmg, about 1,5 MB)

After downloading, drag the program from the image to your 'Applications folder'.


Download it here for Mac OS 7.6.1 through 9.2.2:

MariMaxCor 3.5 (*.sit, about 750kB, Stuffit Expander required)

Run the program from any location on your hard drive.

Both packages include a short readme in English and Dutch in which the workings of the program are explained.

 

Is there any other documentation available about MariMaxCor ?

There sure is. An explanation of the MariMaxCor algorithm is available in English:

Aside from that, the original report on MariMaxCor:
Elshout, J. J., Elshout-Mohr, M. & van de Wijgaart, P. (1969). Marimaxcor: hiërarchische clusteranalyse uitgaande van een intercorrelatiematrix (FL.14.11.69.004). Amsterdam: Afdeling Functieleer, Instituut voor cognitieonderzoek, Universiteit van Amsterdam. is available as *.pdf in Dutch only:

Who are responsible for MariMaxCor?

The MariMaxCor algorithm was devised in the 1960's of last century by Jan Elshout, now emeritus professor of Psychology at The University of Amsterdam, and his associates.

After previous versions of the program running on various computer systems, Mark Rietveld wrote the final version of MariMaxCor for the Macintosh in 2002. Ronald Hamel provides the space for these pages.
