Kick-off for Chemometrics.se PDF Print E-mail
Written by Johan Trygg   
I am very pleased to announce the official kick-off for Chemometrics.se. You will recognize many "old" features such as the popular Tutorial section, but we have also added a new Editorial section, with more focus on being an Editorial, rather than a tutorial.
In addition, we have a section called "Latest News", where you the visitor is an important contributor. If you create a login account (for free of course and the information will NOT be passed on to third parties), you can submit news of interest to the reader of Chemometrics.se if you click on "Submit News" button. After it is submitted it will be checked for spam and then published on this website under "Latest News". You can also submit conference reports (incl uploading images) under "Submit Conference Report". Due to the technical improvement of Chemometrics.se, anyone, not just those familiar with html code and ftp are able to be actively involved. All is done via the Chemometrics.se website and forms to fill out, can't be much simpler than that. In addition,  the registered users will automatically receive information of new additions to the Editorial and Tutorial sections. However, the recognised and very appreciated Discussion Forum was spammed to bits, and I will try my best to bring it back to life again.

Once, again, welcome to Chemometrics.se, 
Yours sincerely,
Johan Trygg, Umeå University

Can we use the regression coefficient profile for selecting PLS components?
The linear model y=Xb + f is often used in chemometrics. Unfortunately, we have put too much emphasis on the importance of the regression coefficient profile b, and mistakenly assumed or believed that it should be a good estimate of the "pure profile". This is not true, and I will argue why in later editorials. But this time, I want to address an earlier question that was posed in relation to the regression coefficient profile.

Multivariate Solutions to Metabonomic Profiling and Functional Genomics, Part 2
Simple, unsupervised chemometric methods obviously work well for data sets with a limited number of well-defined classes. However, biological systems are seldom simple and many of the biofluid datasets generated within metabonomics require more sophisticated statistical data analysis.
