New Features in Solo and PLS_Toolbox

Analysis and Models

• MLSCA - Multi-level simultaneous component analysis.
• History now captured in history field of Model Object.
  • Add .scoredistance and .esterror as virtual fields for models.
• ANN now supports custom cross-validation.
• PLSDA varcap plot now available.
• Better handle full-rank PCA sub-models where Q residuals are zero in simca.
• Better handling of errors during variable matching (test to model).
• Better handling of crossval when using PLSDA.
  • Convert plsda regression method input to be 'sim' (to speed it up).
  • Recognize when user has passed single-column (either logical or class) and force it to be multi-column logical.

Plotting

• Improve handling of zoom status in newer versions of Matlab.
• Better handling of font sizes.
• Smarter plot style (e.g., scatter vs. bar) assumptions in "automatic" mode.
• Fix rearranging of controls issue with newer versions of Matlab.
• ********{REV 19448} add viewcompressgaps option?
• Connect Classes button has drop-down menu to display connection types.
• Add logic to NORMALIZE score distance to maximum calibration value.
• Respect include field when calculating scores limit
• Show knn score distance limits on plotscores plots.

Importers

• omnicreadr - Reads OMNICix HDF5 image files.
• Improved importer behavior with mixed length data using matchvars during import.
• Updated libraries to use new labspec 6 components including 64 bit support.
• xlsreadr - Add support for joining sheets in rows using matchvars.
  • Add support for using the same graphically-selected parsing options on ALL sheets.

Preprocessing

• glog Generalized Log Transform added to preprocessing options.
• pqnorm Probabilistic Quotient Normalization added to preprocessing options.
• ******{REV r19390} glsw Combine ELS/EMM and EPO options (use "inf" to select all PCs to get old ELS behavior)
• Add support for handling missing data in both normaliz and mscorr (median only).

Distribution Fitting Toolbox

• kurtosis: Added kurtosis statistic function.
• skewness: Added skewness statistic function.

Other Interfaces

• Multiblock Tool - Interface to view, manipulate, and join data.
• Model Optimizer - Better handling of numeric data in comparison table, additional statistics, and improved handling of include field.
  • Add support for automatically using user-selected model groupings in PLSDA and SVMDA within model optimizer.
• Better help integration with newer version of Matlab.
• Hierarchical Model Builder - Add vertical scrolling.

New Command-line Features and Functions

Misc New Functions

• eemoutlier - New function for automatically removing outliers in fluorescence PARAFAC models.
• mlsca Multi-level Simultaneous Component Analysis.
• multiblock Create or apply a multiblock model for joining data.

Command-Line Changes

• matchvars - Add logic to speed up some cases of joins.
• mdcheck - Allow use of KNN as data replacement method (replace missing data with data from sample(s) which are closest).
• jmlimit - Better handle degenerate cases when multiple confidence levels are requested (return VECTOR of zeros instead of single zero).
• cov_cv - Changed from SVDS to SVD.
• histaxes - Fix for when NaN's are present in data.
• als - Sort components by variance captured (if no constraints otherwise defining order).
• confusionmatrix - Report additional quantities for each class: count, classification error, precision and F1 score..
  • Standardize terminology: TP = count, TPR = proportion (rate) for confusion matrix quantities, and labels shown.
• comparemodels - Report the mean (class count weighted) of Classification Error, Precision, F1 Score for classification models.
