New Version 4.3.1 released 8/23/11. It runs only under JMP version 9.0 and later.
Updated Basic Functions for Version 4.3.0
- Supports robust and regular singular value decomposition
- Supports four algorithms for non-negative matrix factorization + sparsity options
- Provides visualization, heatmaps, score plots of the factorization
- Gives a novel method to judge the number of NMF factors
- Provides fitted and residual matrices
- Effects a clustering of the rows and columns of the matrix
- Provides association statistics between NMF clusters and actual groups, ROC curves
- Gives novel methods of determining which columns can be used to predict class labels that is more powerful than traditional methods
- New user interface
