Development and Evaluation of a Digital Expert Elicitation Method
The paper describes an elicitation procedure which opens up many opportunities to investigate tacit differences between “subjective” teacher judgments and “objective” data such as test results and to raise the diagnostic competence of teachers.

Can you help us (Rens and Herbert) to make a list of journals for which no fees have to be paid (not by authors, readers or universities/libraries/funders) and with a high enough quality you would want to publish your work in it. So far we…
Symposium Systematic Reviewing 3.0
Scopus search of researchers working at Utrecht University who published with ‘systematic review’ in the title. In total, 283 of these papers have been published in 2018. Systematic Reviews are “top of the bill” in research. The number of systematic reviews published by researchers increases year…
Testing Small Variance Priors Using Prior-Posterior Predictive P-values
Muthen and Asparouhov (2012) propose to evaluate model fit in structural equation models based on approximate (using small variance priors) instead of exact equality of (combinations of) parameters to zero. This is an important development that adequately addresses Cohen’s (1994) “The earth is round (p < .05)”, which stresses that point null-hypotheses are so precise that small and irrelevant differences from the null-hypothesis may lead to their rejection.
Deelname onderzoek lvs-CITO scores
We zijn op zoek naar (parttime* en fulltime) PO docenten groep 3 t/m 7, die gebruik maken van het CITO LVS systeem. Aanmeldingen van individuele docenten zijn welkom, maar opgeven met een groep collega’s of zelfs met het hele team is ook mogelijk.
Using the Data Agreement Criterion to Rank Experts’ Beliefs
We evaluated priors based on expert knowledge by extending an existing prior-data (dis)agreement measure, the Data Agreement Criterion, and compare this approach to using Bayes factors to assess prior specification.
Statistical Methods for Small Data
After the publication of our paper Bayesian PTSD-Trajectory Analysis with Informed Priors Based on a Systematic Literature Search and Expert Elicitation in Multivariate Behavioral Research, I was contacted by Scientia whether I was interested in an outreach publication based on our paper. Since I had funding for this…
“Shape sorting” students for special education services?
In this dissertation, we focused on two alternative approaches to evaluate the hypothesis of interest more directly, i.e. informative hypothesis testing and model selection using order-restricted information criteria.
Manipulating the alpha level cannot cure significance testing
We argue that depending on p-values to reject null hypotheses, including a recent call for changing the canonical alpha level for statistical significance from .05 to .005, is deleterious for the finding of new discoveries and the progress of cumulative science.
Mother, father and child traumatic stress reactions after paediatric burn
The current study examined occurrence and within-family associations of traumatic stress reactions after child burn injury, while in the same model addressing the role of parents’ own symptoms in their reports of child symptoms.
