Multimix.for 	contains the program code for fitting a finite 	
		mixture of K groups to the data.

[Missing.for]	contains a version of Multimix.for which can handle 	
		missing values in the variables. [Currently 		
		unavailable while minor changes are being made, 
            enquiries to Lyn Hunt, lah@waikato.ac.nz]

Talk.dvi	Dvi and Postscript versions of a paper presented
Talk.ps		on 23 August 1996 to the conference ISIS96, 
		Information, Statistics and Induction in Science, 
		held in Melbourne, Australia. [Published in the
		proceedings of the Conference, edited by D. L. Dowe,
		K. B. Korb and J. J. Oliver, World Scientific: 
		Singapore]

Notes.ps  	is a postscript file giving information about the 	
		input required to run Multimix. Please read this 	
		file.

Ppaper.ps   A description of Multimix prepared for the proceedings
            of Uncertainty 99, the Seventh International Workshop on
           Artificial Intelligence, Ft Lauderdale, FL, Jan 3-6, 1999.

Paper.dvi   Dvi and PostScript versions of a paper on Multimix to
paper.ps    appear in the Australian and New Zealand Journal of
            Statistics.
Alltables.dvi   Tables for the above paper.
Alltables.ps

Read3.for 	contains program code for setting up a 
		parameter input file for program Multimix. This is
		useful when setting up the first few runs with a data
		set. Later it is easier to modify existing files
		with a text editor.

Flexi		This subdirectory contains a Bayesian smoothing 
		program written by Martin Upsdell. It is not connected
		with Multimix in any way. Read about Flexi in
		Flexi/Info.txt. Martin's email address is

EXAMPLE OF DATA FILE, INPUT FILE, AND OUTPUT FILES

Cancer11.dat 	contains the cancer data file as used by the
                  program. Some variables are transformed.

Cancer data.txt   not intended as an input file, this version of
                  the cancer data contains the clinical
                  classification into stages 3 and 4.

Cancerdesc.txt	A description of the data in Cancer11.dat.

2band.dat 	contains a parameter input file for the cancer data. 
		A two-component mixture model is to be fitted. The
		variables are partitioned into blocks. Each block or
		'cell' is assumed independent of the others within
		each component. In the model fitted by 2band.dat
		the distributions of the variables in each block are
		1	Univariate Normal
		2	3-category Discrete
		3	2-category Discrete
		4	Trivariate Normal
		5	7-category Discrete
		6	Univariate Normal
		7	Univariate Normal
		8	Univariate Normal
		9	Univariate Normal
		10	2-category Discrete
		There is some re-ordering of variables to make the
		variables in each block contiguous. An initial grouping
		of the observations into two clusters is specified.
		Alternatively initial parameter values could have
		been given.

General.out 	is the output file generated when using the parameter 
		file 2band.dat.

Groups.out 	contains the group assignment and the posterior 		
		probabilities of assignment to the two groups when 	
		using the parameter file 2band.dat.

mm.zip      All of the above, zipped.
