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

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

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

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

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

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)

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...
