Hey #Bayes folks, I have the following prior:

A ~ N(m1,v1)
B ~ N(m2,v2)
A > B (Or A - B > 0)

What would you call the last specification?

I've seen these called inequality constraints, order restrictions, stratification, hyperpriors...

Great Clips Monster Jam driver Bryce Kenny and his co-worker Adam use Clip Notes to get the same great haircut every time! 👏

I am teaching model building/ variable selection using DAGs in my regression course.

I'd love to provide a few different real-world examples of the consequence of conditioning on a collider. Does anyone have a favorite teaching example? #epitwitter #statstwitter

Q #StatsTwitter 🙋🏾‍♂️

When deriving prediction model, in absence of ext validation dataset, one should report optimism-adjusted performance. Both int validation (eg bootstrapping) and penalised regression (eg ridge) can adjust for optimism.

Is one method preferred over other? 🙏🏾

Petition to officially rename 'violin plots' as 'vulva plots'.

PS the younger folk in the room should note that violin plots come in many different shapes and sizes.

#statstwitter #brms . Question: I have a GAM model that I want to fit with brms. The data comes from a skiing experiment where skiers ski multiple runs in three different slalom courses (A, B, and C) on the baseline and later retention test (1/n)

#EpiTwitter #StatsTwitter What is the rationale for using discrete-time survival analysis for prediction? If you have continuous follow-up time why would you split it into intervals?

Prognostic modelling question—if you have a dataset containing both non-fatal and fatal CHD events, and you want to develop a time-to-event model for predicting non-fatal CHD specifically, how should CHD deaths be dealt with (assuming they're not rare)? #EpiTwitter #StatsTwitter

My statistical test assumes that I randomize.

I indeed randomize.

Do I need to do a balance test to check whether the randomization “worked”?
