Happy to share that our large-scale network analysis is now out in @nathumbehav.nature.com
We show that networks are often supported by too little evidence from the data for results to be reported with confidence, not meaning that results are flawed but rather suggests caution in interpretation.

Psychometric network models have become increasingly popular in psychology and the social sciences. Huth et al. show that many reported network findings are based on weak or inconclusive evidence inviting caution when interpreting results.

Two new preprints on multilevel HMMs! Time series data is now pervasive in psychology and new methods are needed to model the dynamics in such data. Hidden Markov Models (HHMs) are powerful models for dynamics in which a system is switching between a number of discrete states.
