Each episode of The Data Science Podcast with Fexingo is a grounded, specific conversation about a single analytics problem or machine-learning method — from regularization in regression to the bias-variance trade-off in random forests. Lucas leads with a journalistic eye for how models are built and tested in the real world, citing actual case studies like how Netflix used matrix factorization for recommendations or how healthcare researchers apply survival analysis to clinical trials. Luna keeps the discussion honest, asking about data quality, feature engineering pitfalls, and whether a model’s accuracy actually translates to business value. They never resort to buzzwords: instead, they walk through the workflow from data collection to deployment, discussing trade-offs like interpretability versus performance. The show serves data scientists, analysts, and engineers who want to stay sharp on methods without the hype. Listeners walk away with a clearer understanding of why one algorithm beats another on a gi…","last_synced_at":"2026-07-19T08:17:23.323447+00:00","page_url":"https://stenobird.com/podcast/the-data-science-podcast-with-fexingo-analytics-machine-learning-and-data-driven-conversations-7871831"},"episode":{"title":"How Data Scientists Use Bayesian A-B Testing for Better Decisions","slug":"how-data-scientists-use-bayesian-a-b-testing-for-better-decisions","published_at":"2026-06-18T20:24:03+00:00","page_url":"https://stenobird.com/podcast/the-data-science-podcast-with-fexingo-analytics-machine-learning-and-data-driven-conversations-7871831/how-data-scientists-use-bayesian-a-b-testing-for-better-decisions","show_page_url":"https://stenobird.com/podcast/the-data-science-podcast-with-fexingo-analytics-machine-learning-and-data-driven-conversations-7871831","url":"https://audio.fexingo.com/business/the-data-science-podcast/episode-0059.mp3","audio_url":"https://audio.fexingo.com/business/the-data-science-podcast/episode-0059.mp3","summary":"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","meta_description":"Lucas and Luna explore why traditional A/B testing falls short when data is sparse or you need to compare more than two variants.
