To celebrate the openESM paper release, I wrote a brief blog post summarizing recent developments: openesmdata.org/blog/2026-07... We: 💠added more data 💠provided descriptive visualizations for each item 💠created a semantic similarity mapping for items, making it easier to find related items

openesmdata.org

Updates: Paper published, new dataset & features

Our tutorial paper on openESM has been published, and we have added new datasets and features to the platform.

Image with three main boxes with recommendations for applied researchers on conceptualization, estimation, and interpretation when using network features.
Conceptualization:
- Discuss why a network feature should be relevant for a given treatment or outcome
- Consider plausible effect size and sample size needed to detect an association with a distal outcome

Estimation:
- Carefully choose preprocessing and network estimation methods
- Follow good practices for predictive models (e.g., cross-validation, out-of-sample validation)

Interpretation:
- Consider uncertainty in node selection and network feature regression
- Compare network features with simpler time series features (e.g., person-specific mean or SD)
