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”.


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.
