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","slug":"how-data-scientists-use-bayesian-a-b-testing","published_at":"2026-06-08T07:56:33+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","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-0038.mp3","audio_url":"https://audio.fexingo.com/business/the-data-science-podcast/episode-0038.mp3","summary":"Lucas and Luna dive into Bayesian A/B testing, a method that's quietly replacing traditional frequentist approaches in data science. They break down how it works, why it's more intuitive, and where it falls short. The episode centers on a real case: how a major retailer used Bayesian testing to optimize their checkout flow, cutting decision time from weeks to days. Lucas explains the math behind prior probabilities and posterior distributions without the jargon, while Luna questions whether Bayesian methods can really scale in big-tech environments. They also touch on the common pitfalls, like choosing a bad prior or misinterpreting results. By the end, listeners will understand the key difference between 'is this statistically significant?' and 'what's the probability this variant is better?'—and why the latter question is often more useful in practice. #DataScience #Technology #BayesianStatistics #ABTesting #MachineLearning #StatisticalModeling #DataDrivenDecisionMaking #PriorProbability #PosteriorDistribution #ConversionRateOptimization #FrequentistVsBayesian #DataSciencePodcast #FexingoBusiness #BusinessPodcast #Experimentation #DecisionScience #EcommerceAnalytics #DataCulture Keep every episode free: buymeacoffee.com/fexingo","meta_description":"Lucas and Luna dive into Bayesian A/B testing, a method that's quietly replacing traditional frequentist approaches in data science.
