Leverage the Full Power of Bayesian Analysis for Competitive Advantage

Bayesian methods can solve problems you can't reliably handle any other way. Building on your existing Excel analytics skills and experience, Microsoft Excel MVP Conrad Carlberg helps you make the most of Excel's Bayesian capabilities and move toward R to do even more.

Step by step, with real-world examples, Carlberg shows you how to use Bayesian analytics to solve a wide array of real problems. Carlberg clarifies terminology that often bewilders analysts, provides downloadable Excel workbooks you can easily adapt to your own needs, and offers sample R code to take advantage of the rethinking package in R and its gateway to Stan.

As you incorporate these Bayesian approaches into your analytical toolbox, you'll build a powerful competitive advantage for your organization—and yourself.

  • Explore key ideas and strategies that underlie Bayesian analysis
  • Distinguish prior, likelihood, and posterior distributions, and compare algorithms for driving sampling inputs
  • Use grid approximation to solve simple univariate problems, and understand its limits as parameters increase
  • Perform complex simulations and regressions with quadratic approximation and Richard McElreath's quap function
  • Manage text values as if they were numeric
  • Learn today's gold-standard Bayesian sampling technique: Markov Chain Monte Carlo (MCMC)
  • Use MCMC to optimize execution speed in high-complexity problems
  • Discover when frequentist methods fail and Bayesian methods are essential—and when to use both in tandem
