Pushing the Limits
The Performance of Maximum Likelihood and Bayesian Estimation With Small and Unbalanced Samples in a Latent Growth Model is compared in a simulation study
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...
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)...
A comparison of the single, conditional and person-specific standard error of measurement
Tests based on the Classical Test Theory often use the standard error of measurement (SEm) as an expression of (un)certainty in test results. Although by convention a single SEm is calculated for all examinees, it is also possible to (1)...

“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...
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.
LofS videos
In the fall of 2018, De Jonge Akademie will launch an interactive platform titled ‘The Living Room of Science’ (LofS) for generating, gathering and sharing knowledge on responsible research practices across all research disciplines. This platform will help young scholars...
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.
Bayes with Informed Priors Based on Literature and Expert Elicitation
