Chemometric software updates

Eigenvector Research has released PLS_Toolbox and Solo 8.6, and with them a new interface for variable selection. They have integrated Interval PLS (iPLS), Recursive PLS (rPLS), Genetic Algorithm (GA) and two methods based on Variable Importance in Projection (VIP) and Selectivity Ration (SR) into the main analysis interface. They have also developed an Automatic mode based on VIP and SR that performs a search to optimise the selection without additional user input.
