29th Annual Chemometrics Symposium
“How to handle missing and censored data”
Thursday 15th October 2015, Wageningen, The Netherlands
Most recipes for data analysis assume that data are complete and have been measured accurately. In real life this often is not the case. Data can be missing, which means that they have not been measured at all. Or they may be censored, which means that they are known to be less (or sometimes larger) than a given threshold. Both cases need special treatment.
The Dutch Chemometrics Society invites you to their Annual Chemometrics Symposium 2015 that will focus on handling missing and censored data. We are proud to present a program with excellent speakers, who will discuss theory and practical applications.
Speakers with their presentation titles:
• Stef van Buuren
“Multiple imputation of incomplete multivariate data: a bird’s eye view”
• Hae-Won Uh
“Dealing with data below the detection limit: a statistical view on uncertainty”.
• Jeroen Elassaiss-Schaap
“Mixing censoring into population PK and PK-PD nonlinear mixed effects”
• Gerjen Tinnevelt
“A PLS-based approach to combine multiple flow cytometry tubes”.
• Martin Lopatka
“Novel data imputation to emulate complex mixing condition seen in fire debris samples”.
• Jos Hageman
“Batch correction for LCMS in the presence of non-detects”.
Location
The meeting will take place in meeting room C103, Forum, building number 102, Droevendaalsesteeg 2, 6708 PB Wageningen, The Netherlands. See Forum-building-number-102 for a description and how to get there.
Time
Registration and coffee between 9:15 and 9:55, opening symposium at 9:55.
Fee
The registration fee is 100 euros (50 for students and PhD students). Everything is included: participation in the meetings, lunch, refreshments and drinks at the end of the day. It is not possible to register for a half-day at a reduced price.
Language

7th International Chemometrics Research Meeting
ICRM2017
September 10th - 14th 2017
Fletcher Parkhotel Val Monte
Berg en Dal, The Netherlands
The International Chemometrics Research Meeting is organized every three years (by the Dutch Chemometrics Society). It is dedicated to in-depth discussion of recent chemometric and statistical developments that are relevant to analytical chemistry and is applications. The format of the meeting is inspired by the Gordon conferences: two sessions per day (one in the morning and one in the evening), with an invited speaker, a discussant and lots of room for the floor discussion.
Participants can bring posters and there is room for a small number of contributed talks.
New this time are 4 short tutorials, on ASCA, PCA/PLS, penalties and on MCR. The tutorials take place in the afternoons. They do not overlap and attendance is free for conferences participants.
A social program and conference dinner is also part of ICRM2017.
The following invited speakers will give a keynote lecture:
- Peter Wentzell (Dalhousie University, Halifax, Canada).
- Lieven De Lathauwer (KU Leuven, Belgium).
- Peter Filzmoser (TU Wien, Austria)
- Morten Rasmussen (University of Copenhagen, Denmark)
- Marieke Timmerman (RU Groningen, The Netherlands)
- Onno de Noord (Shell Amsterdam, The Netherlands)
- TBA
This is a first announcement. More information about registration and the conference fee will follow soon.

30th Annual Chemometrics Symposium
“Chemometrics in Action”
Thursday 13th October 2016, Ravenstein, The Netherlands
The Dutch Chemometrics Society cordially invites you to its Annual Chemometrics Symposium. This year the theme is “Chemometrics in Action” with a focus on practical applications. Six speakers will cover a variety of subjects. During the lunch a microNIR spectrophotometer will be demonstrated.
As usual, this symposium will be an excellent opportunity to meet old and new colleagues, to learn new things and to discuss them in an informal and friendly atmosphere.
Speakers with their presentation titles
• Rudolf Kessler
“Perspectives in Process Analysis: Remarks on Robustness of Spectroscopic Methods
for Industrial Applications
• Jan Gerretzen
“A novel and effective way for preprocessing selection based on Design of Experiments”.
• Andrei Barcaru
“Thinking Bayes: creating new ways of interpreting GCxGC(-MS) data”.
• Cyril Ruckebusch
“Chemometric analysis of chemical images”.
• Olga Lushchikova
“Development of alarm system for water quality control based on flow cytometry data
of algal populations”.
• Ewoud van Velzen
"Robustness: A key parameter in the validation of multivariate sensory regression
models”.

About DCS
The history of the Dutch Chemometrics Society starts in 1972, with the merger of the discussion groups "Automation" and "Computerization" into the "Laboratory Optimization" group of the Royal Netherlands Chemical Society. This discussion group, which was driven by first generation chemometricians like A. Dijkstra, G. Kateman and H.C. Smit, was later re-named into the "Working Party on Chemometrics", which also functions as the Dutch Chapter of the International Chemometrics Society. Two important initiatives taken by this group were the organization of a series of short courses on chemometrics for industry and the start of a series of international conferences on chemometrics in analytical chemistry (CAC). CAC I (1978), II (1982) and IV (1988) were held in The Netherlands.
Present activities of the Dutch Chemometrics Society include an annual symposium on chemometrics, workshops on more focused topics, as well as contributions to activities of (other working parties of) the Royal Netherlands Chemical Society. The symposium follows a "classical" format, whereas the workshops present a forum for advanced, in depth discussion in a very informal setting. With the dissemination of chemometrics into industry and institutes the need for such workshops grew rapidly, since chemometricians rarely find discussion partners in their immediate working environment. In 1989 three such workshops, one on Multivariate Data Analysis (MVA workshop), one on Experimental Design and Optimization, and one on Quality Assurance started with a meeting frequency of three times per year. The latter two workshops dried out of new topics, but the Multivariate Data Analysis Workshop is still going strong. In 2005, a new discussion group was started with a focus on the analysis of proteomics and metabolomics data (Bio-MVA workshop).
The second generation chemometricians also started a new conference series: the International Chemometrics Research Meeting (ICRM), which was held in The Netherlands in 1994, 1998, 2002, 2006, 2011, 2014 and 2017. ICRM has a format which makes it complementary to other conference series in this field. Key elements are: extended exchange of ideas in an informal atmosphere, limited number of lectures on a few selected topics, scheduled plenary discussion sessions, plenty of time for informal discussion, and continuous poster display.
Participants to the Dutch Chemometrics Society activities come from universities (40%), industry (40%) and institutes (20%).
