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.] 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. 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 upsdellm@agresearch.cri.nz. EXAMPLE OF DATA FILE, INPUT FILE, AND OUTPUT FILES Cancer11.dat contains the cancer data file. 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. Queries to Murray Jorgensen .
