The Bayesian concept makes the link between the prior probability of observing a conversion rate value , and the posterior probability of observing this knowing the number of visitors n and. Bayesian Inference in Python with PyMC3 To get a range of estimates, we use Bayesian inference by constructing a model of the situation and then sampling from the posterior to approximate the posterior.

Data Analysis is the technique to collect, transform, and organize data to make future predictions, and make informed data-driven decisions. Take your first steps in the Bayesian world. While EDA was originally thought of as something you apply to data before doing any complex analysis or even as an alternative to complex model-based analysis, through the book we will learn that EDA is also applicable to understanding, interpreting, checking, summarizing, and communicating the results of Bayesian analysis.
