===Model Building===
===Model Building===
* SVM
* Support Vector Machine Regression and Classification non-linear modeling methods available in Analysis GUI (Solo and PLS_Toolbox) and command-line (PLS_Toolbox).
* LWR
* Locally Weighted Regression (LWR) non-linear modeling method available in Analysis GUI and significantly revised at the command-line to add new features, preprocessing support, and compatibility with Solo_Predictor 2.1
* Permutation test added to Analysis GUI to allow easy testing for over-fit regression models (randomized y-block).
* TrendTool outputs model structures which can be used to make predictions on new data and are compatible with Solo_Predictor 2.1. Interface is also now accessible through [[EVRIGUI_Objects]]
* PLS-DA prior probability settings now available in Analysis GUI.


===Scores Plots===
===Scores Plots===
* KNN Score Distance metric available in scores plots of PLS, PCR, and PCA ([[knnscoredistance]]).
* Prediction intervals (Estimated prediction error) accessible in Scores plots
* Improved handling of class modifications.


===Preprocessing===
===Preprocessing===
* Kaiser Optical Systems HoloReact method importer to create preprocessing from band-area methods ([[hrmethodreadr]]).
* Add "Transmission to Absorbance" preprocessing method (-log10(T)).
* GLSW/EPO: add "meancenter" option to better handle orthogonalization to specific clutter matrix, plus improved help ([[glsw]]).
* Improved memory and speed performance for various preprocessing methods.
* Custom [[SpectraQuant_Filtering| SpectraQuant Filtering algorithm]] for background correction (available only through Hamilton Sundstrand)


===Importers/Exporters===
===Importers/Exporters===
* Experiment File Importer - reads file containing filenames and reference measurement data and imports the corresponding files and data into Analysis GUI. Automatically assigns the data to X and Y and to calibration and validation blocks ([[experimentreadr]]).
* Analytical Spectral Devices (ASD) Indico (Versions 6 and 7) data file reader added.
* Hamilton Sundstrand PIONIR PDF file importing added ([[pdfreadr]]).
* Horiba JY file importer fixes to data type handling and converts all data to double precision when importing.
* Horiba JY file importer performance and support for large files improved ([[hjyreadr]]).
* Fix Excel reader problem which makes some XLS files unreadable on 64-bit systems.
* SPC file importer reads file comments ([[spcreadr]]).
* Support for combining multiple DataSets. Selecting multiple items in Workspace Browser provides access to new "combine" menu option.
* XY file importing performance improved ([[xyreadr]]).
* XML importing/exporting support and performance improved ([[parsexml]] / [[encodexml]]).
* Improved support for manual parsing of CSV files ([[xclreadr]]).
* Export Data to Analect Spectral Files (ASF) ([[writeasf]]).
* Export Data to simple CSV file format for non-DataSet objects ([[writecsv]]).
* Export regression Models to CPSA32/PC80 .tbl format  (available only through Hamilton Sundstrand).


===Other Enhancements===  
===Other Enhancements===  
* Plot Controls: Full access to all items in a DataSet (no longer limited by number of rows or columns)
* Demo datasets now easily available in Model Cache.
* BoxPlot: new box plot function (PLS_Toolbox only) to allow better coexistance with Statistics Toolbox (R) from The Mathworks ([[boxplot]])
* Clearer deliniation of method categories and access to help in Analysis GUI.
* Toolbars: Toolbars are now present on most interfaces and plots to make standard actions and interaction between GUIs easier.
* Improved appearance and Copy/Paste functionality for MAC and Linux platforms.
* TrendTool: Improved interactivity and functionality.
* NND Score Distance calculation now uses Mahalanobis distance
