The past we study is shaped by what survived - but what about everything that didn't? The CHR journal wants your work on measuring, understanding, and accounting for missing data.

Deadline has been extended to Jan 31, 2025. Guest-edited by @zoeleblanc.bsky.social and @mikekestemont.bsky.social

The effects of the covariates are limited. Is this reality or data limitation? We tried to do quite an extensive model comparison, which revealed high uncertainty. When modeling stuff that's unknown, that's a good thing!

While adding covariates (age, gender, origin) modestly improved estimates compared to basic Chao1, the effect was smaller than expected. The Brussels data suggests demographic factors alone may not fully explain historical "visibility patterns."

Using Brussels' Amigo prison records as our case study, we model heterogeneity in detection rates. This does two things: (1) potentially improves population estimates by accounting for sampling bias, and (2) reveals patterns in who gets recorded.

🧵 Building on our previous work with unseen species estimation in historical data: what happens when we add demographic covariates to the model? New findings from 1879-80 Brussels police records in #CHR2024. (with @mikekestemont.bsky.social and Margo de Koster)
