Multivariate Analysis Add-in

We are pleased to be able to offer an add-in for the popular spreadsheet software Microsoft Excel. The package features a user-friendly interface for common chemometric methods such as PCA (Principal Component Analysis), PCR (Principal Component Regression), PLS (Partial Least Squares), and MLR (Multiple Linear Regression).

A free Evaluation Version of the add-in is available for download. The evaluation version is identical to the full version with four exceptions: -

  1. Matrices are limited to a maximum size of 20 rows and/or 20 columns;
  2. The number of components calculated in PCA, PCR, and PLS is limitted to 4;
  3. No documentation is provided;
  4. The VBA interface has been removed, so you cannot call the functions from your own code


If you wish to obtain the Registered Version of the add-in, please complete this online form, and a member of the chemometrics group will contact you in due course.

System requirements:
Microsoft Windows 98, ME, NT4, 2000, or XP.
