Version 0.4-1 released!

We’ve just released version 0.4-1, a minor release that fixes some logistical issues and adds a bit of functionality to our MCMC engine.

Changes as of Version 0.4-1 include:

  • added an elliptical slice sampler to the MCMC engine,
  • fixed bug preventing use of nimbleFunctions in packages depending on NIMBLE, and
  • reduced C++ compiler warnings on Windows during use of compileNimble.

We have a post-doc opening.

We have a 1-year opening for a post-doc interested in developing statistical methods in NIMBLE.

Here is the official, approved job advertisement:

POSTDOCTORAL SCHOLAR POSITION AVAILABLE IN COMPUTATIONAL STATISTICS – UNIVERSITY OF CALIFORNIA, BERKELEY

The Departments of Statistics and Environmental Science Policy, and Management have an opening for a Postdoctoral Scholar – Employee to develop and apply statistical algorithms as part of the NIMBLE software development team. NIMBLE is a NSF-funded framework for programming computational methods for general hierarchical models such as Markov chain Monte Carlo, sequential Monte Carlo, and numerical integration and approximation. More information is available at R-nimble.org. The post- doc will be supervised by co-PIs Perry de Valpine and Chris Paciorek. We seek a candidate who will build out NIMBLE’s algorithm library, which includes using it as a platform for methodological and applied research. The successful candidate will be expected to author peer-reviewed publications and contribute to software development.

BASIC QUALIFICATIONS
Candidates must have completed all degree requirements except the dissertation or be enrolled in an accredited PhD or equivalent degree in a statistical field such as Statistics or Computer Science or a field of statistical application at the time of application.

ADDITIONAL QUALIFICATIONS
Candidates must have a PhD or equivalent degree in a statistical field such as Statistics or Computer Science or in a field of statistical application such as biology, ecology, environmental science, political science, psychology, education, public health or related field by appointment start date.

PREFERRED QUALIFICATIONS
Demonstrated experience programming complex scientific computing applications using R and/or C++, Python or others. Demonstrated experience advancing computational statistical methodology by appointment start date.

APPOINTMENT
The position is available to start immediately but we seek the best candidate even if they cannot start until a later date. The initial appointment is for one-year, with renewal based on performance and funding. This is a full-time appointment.

SALARY AND BENEFITS

Version 0.4 released!

In late July we released a major new version of NIMBLE, 0.4.  Ok, that’s still a low version number, indicating we have a lot we still want to build and improve, but this version can do a lot and is a huge step forward from 0.3.  Almost everything runs faster, from model building to model and nimbleFunction compiling to compiled execution.  New features include the ability to write your own functions and distributions for BUGS (as nimbleFunctions, of course) and an algorithm that automatically adapts blocks of correlated parameters for efficient joint sampling in MCMC.  Read NEWS (link here) for more details.  The same information is also on github (here).
