# Is there any university program that offers an introductory statistical methods class that is bayesian -instead- of a frequentist one?

Is there any university program that offers an introductory statistical methods class that is bayesian -instead- of a frequentist one?

Surely every intro to stats class in every program in the world, whether agronomy or economics or psychology or a service class by the stats department, is primarily frequentist based.

And just as surely there are many (but not all) programs where later in the curriculum there are some specialty courses (requiring a few stats pre-reqs) that are titled 'Intro to Bayesian Statistics'.

But are there at least some places somewhere that offer a bayesian class as the intro statistical methods class? (either as the only intro to stats -or- simply as an alternative first class to a frequentist intro)

I would count an intro stats class that teaches bayesian methods in addition to frequentist ones.

If such programs are not as rare as I imagine, then is there any indication of percentage?

I am wondering how easy it is to have a bayesian methods course without first having a frequentist methods course.

• As suggested at the original question over at stats.SE, McElreath’s textbook "Statistical Rethinking: A Bayesian Course with Examples in R and Stan' would be the start-from-scratch Bayesian methods text to use. – Mitch Oct 7 at 15:33
• I'm finding (and this was the motivation for the original question) that the multitudinous post-grad/practical Masters data science programs are descriptive stats/probability, then NHST/p-values, then OLS and done. Bayesian methods don't even exist. Of course there's an ML component but that's not Bayesian, just random assumption-less regression methods. – Mitch Oct 11 at 17:30
• OLS (and least-squares more generally) can be used in a Bayesian way: in that class I taught at Plymouth University, I used to discuss algebraic formulae that could be applied to the typical output values provided by least-squares fitting software, to obtain the leading-order Laplace's method approximations to the expectation and the marginal standard deviations of the posterior distribution over parameters, and to the marginal likelihood for the model; I also used to present some Gnuplot scripts that implemented those formulae. – Daniel Hatton Oct 20 at 11:00
