#statstab #537 {hdbayes} An R Package for Bayesian Analysis of Generalized Linear Models Using Historical Data
Thoughts: An interesting approach to priors. I'm not v familiar w this so curious what others think.

#statstab #532 Fractional Bayes Factors for Model Comparison Free - O'Hagan (1995)
Thoughts: Use a fraction of the data to convert an improper prior into a minimally informative prior.
#statstab #529 How Do I Know What My Theory Predicts?
Thoughts: I'd like to see more researchers adopt Dienes' framework and way of thinking about research.

The latest #PyDataVenice event took place last week πππ
π Two speakers tackling complex systems: climate networks with a #Bayesian approach, and trading with custom #StrategicRule algorithms.
πΊ Small audience, great #networking over a beer.
β₯οΈ #ThankYou all for making this event possible !!!
