July 4, 2017
By

Many more scripts from DBDA2E have been re-written for Stan, by Prof. Joseph Houpt at Wright State University. Joe has posted his scripts at GitHub: https://github.com/jhoupt/DBDA2EstanTo run Joe's Stan scripts you will need the usual other supporting ...

## Difference of means for paired data: Model the mean of the differences or the joint distribution

June 29, 2017
By

I'm regularly asked about how to analyze the difference of means for paired data, such as pre-treatment and post-treatment scores (for the same subjects), or, say, blood pressures of spouses, etc. The usual approach is merely to consider the difference...

## Bayesian estimation of correlations and differences of correlations with a multivariate normal

June 26, 2017
By

Within days of each other I received two emails asking about Bayesian estimation of correlations and differences of correlations. Hence this post, which presents an implementation in JAGS and R.Traditionally, a joint distribution of several continuous/...

## scala-glm: Regression modelling in Scala

June 21, 2017
By

Introduction As discussed in the previous post, I’ve recently constructed and delivered a short course on statistical computing with Scala. Much of the course is concerned with writing statistical algorithms in Scala, typically making use of the scientific and numerical computing library, Breeze. Breeze has all of the essential tools necessary for building statistical algorithms, … Continue reading scala-glm: Regression modelling in Scala

## Posterior distribution of predictions in multiple linear regression

June 11, 2017
By

In a previous post I showed how to compute posterior predictions from multiple linear regression inside JAGS. In this post I show how to do it after JAGS, in R.There are trade-offs doing it in JAGS or afterwards in R. If you do it in JAGS, then you kno...

## Statistical computing with Scala free on-line course

May 31, 2017
By

I’ve recently delivered a three-day intensive short-course on Scala for statistical computing and data science. The course seemed to go well, and the experience has convinced me that Scala should be used a lot more by statisticians and data scientists for a range of problems in statistical computing. In particular, the simplicity of writing fast … Continue reading Statistical computing with Scala free on-line course

## New version of BEST package (Bayesian estimation of two groups)

May 29, 2017
By

Mike Meredith has updated the BEST package again! CHANGES in v.0.5.0 (2017-05-28) * 'BESTmcmc' uses 'rjags' directly, instead of 'jagsUI' wrappers. This resolves 'set.seed' issues, but values returned will not be the same as with previous version...

## Looking for great teachers of Bayesian statistics

By

I'm looking for great teachers of Bayesian statistics! Have you taught a course in Bayesian statistics? Have you used DBDA2E? Are you an enthusiastic teacher with very high evaluations?Do you have an abiding interest in a range of applied sta...

## Bent Coins for a Twisted Mind

May 4, 2017
By

Ben Motz voluntarily sat through an entire semester of my Bayesian stats course. In karmic retribution, after the conclusion of the course he surprised me with a set of biased coins that he designed and created with the amazing craftsmanship of Jesse ...
