NEW FEATURES

Compatibility

• Updated for Matlab 2010a compatibility.

Model Building

• Support Vector Machine Regression and Classification non-linear modeling methods available in Analysis GUI (Solo and PLS_Toolbox) and command-line (PLS_Toolbox).
• 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

• Prediction intervals (Estimated prediction error) accessible in Scores plots

Preprocessing

• Add "Transmission to Absorbance" preprocessing method (-log10(T)).

Importers/Exporters

• Analytical Spectral Devices (ASD) Indico (Versions 6 and 7) data file reader added.
• Horiba JY file importer fixes to data type handling.
• Fix Excel reader problem which makes some XLS files unreadable on 64-bit systems.

Other Enhancements

• Demo datasets now easily available in Model Cache.
• Clearer deliniation of method categories and access to help in Analysis GUI.
• Improved appearance and Copy/Paste functionality for MAC and Linux platforms.
• NND Score Distance calculation now uses Mahalanobis distance
• Improved Copy/Paste functionality from DataSet Editor data table (labels included and formatted for Excel compatibility)
• Improved "single-window" feature - have all PLS_Toolbox or Solo windows "docked" in a single frame.
