How Data Scientists Use Bayesian A-B Testing for Better Decisions
from The Data Science Podcast with Fexingo: Analytics, Machine Learning, and Data-Driven Conversations Hosted by Fexingo
Lucas and Luna explore why traditional A/B testing falls short when data is sparse or you need to compare more than two variants. They walk through a concrete example: a subscription site testing four pricing tiers with only 2,000 visitors per variant. Using Bayesian methods with a Beta-Binomial conjugate prior, the team got actionable probability estimates in three days instead of waiting two weeks for frequentist significance. They cover prior selection, posterior distributions, and the practical business trade-off between speed and certainty. Tune in to learn why Bayesian A/B testing is becoming standard at companies like Booking.com and Etsy. #BayesianABTesting #DataScience #A_BTesting #BetaBinomial #PriorDistribution #PosteriorProbability #FrequentistVsBayesian #BusinessDecisions #Experimentation #PricingOptimization #Bookingcom #Etsy #Technology #MachineLearning #Statistics #FexingoBusiness #BusinessPodcast #DataDriven Keep every episode free: buymeacoffee.com/fexingo
