A Computationally More Efficient Bayesian Approach for Estimating Continuous-Time Models

Hecht, Martin; Zitzmann, Steffen

Continuous-time modeling is gaining in popularity as more and more intensive longitudinal data need to be analyzed. Current Bayesian software implementations of continuous-time models suffer from rather high, inadequate ...

Examining the Presence and Determinants of Operational Momentum in Childhood

Knops, André; Zitzmann, Steffen; McCrink, Koleen

The operational momentum (OM) effect describes a systematic bias in estimating the outcomes of simple addition and subtraction problems. Outcomes of addition problems are overestimated while outcomes of subtraction problems ...

Integrating out nuisance parameters for computationally more efficient Bayesian estimation

Hecht, Martin; Gische, Christian; Vogel, Daniel; Zitzmann, Steffen

Bayesian estimation has become very popular. However, run time of Bayesian models is often unsatisfactorily high. In this illustration, we show how to reduce run time by (a) integrating out nuisance model parameters and ...

Prior Specification for More Stable Bayesian Estimation of Multilevel Latent Variable Models in Small Samples: A Comparative Investigation of Two Different Approaches

Zitzmann, Steffen; Helm, Christoph; Hecht, Martin

Bayesian approaches for estimating multilevel latent variable models can be beneficial in small samples. Prior distributions can be used to overcome small sample problems, for example, when priors that increase the accuracy ...
