“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...

Drijfveren
Voor een project van De Jonge Akademie (DJA) is ons gevraagd hoe we in de wetenschap terecht zijn gekomen en wat onze drijfveren zijn. Benieuwd hoe ik na diverse omzwervingen terecht ben gekomen waar ik nu werk? Ik kan het...
Reduction in sample size by order restrictions
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.
Any new literature on Approximate MI?
I will give a lecture on “Testing for measurement invariance: tips, tricks and what to do if MI does not hold?” including the new method of approximate MI. Are there any recent findings on approximate MI which I should not...
