A Computationally Efficient Projection-Based Approach for Spatial Generalized Linear Mixed Models

Yawen Guan
Pennsylvania State University

Inference for spatial generalized linear mixed models (SGLMMs) for high-dimensional non-Gaussian spatial data is computationally intensive. The computational challenge is due to the high-dimensional random effects and because Markov chain Monte Carlo (MCMC) algorithms for these models tend to be slow mixing. Moreover, spatial confounding inflates the variance of fixed effect (regression coefficient) estimates. Our approach addresses both the computational and confounding issues by replacing the high-dimensional spatial random effects with a reduced-dimensional representation based on random projections. Standard MCMC algorithms mix well and the reduced-dimensional setting speeds up computations per iteration. We show, via simulated examples, that Bayesian inference for this reduced-dimensional approach works well both in terms of inference as well as prediction; our methods also compare favorably to existing "reduced-rank" approaches. We also apply our methods to two real world data examples, one on bird count data and the other classifying rock types. This is a joint work with Murali Haran.

The Mesa Lab semi-annual building maintenance shutdown is scheduled for Saturday, 8 October from 6:00 a.m. until 6:00 p.m.  During this time the Mesa Lab and Fleischmann Buildings will experience intermittent electrical, heating, and air conditioning interruptions, some for extended periods.

Access to the Mesa Lab will be restricted to authorized employees, and there will be no public access to the building.  Visitors may still use the trails around the building.

CISL will be releasing information regarding the impact of the Mesa Lab Data Center portion of the shutdown in the near future as details become available.

For Mesa Lab Data Center questions, contact Jasen Boyington, ext. 1859 or jasenb@ucar.edu.

AGU is conducting a free workshop to help scientists share their science with the public and policy makers in a clear and engaging way. The hands-on workshop will help scientists prepare compelling remarks for their target audience, and learn how to handle controversial topics or unreceptive audiences.

Date: Oct. 19
Time: 12:30 p.m. to 5 p.m. (Lunch is provided at 11:30)
Location: Colorado State University, Lory Student Center, Room 312
Registration details here.  (Seating is limited)

In addition, the AGU Sharing Science program is looking for scientists with experience in science communication to serve as mentors to graduate students at the 2016 Fall Meeting (Dec. 12-16 in San Francisco). Click here if interested or if you have questions, email sharingscience@agu.org

There is still time to register for this course: Generations Working Together

Date: 9/28/16

Time: 1:00 PM - 4:30 PM

Location: FL2-1002

Objective:

To help participants recognize and gain a greater understanding of the unique needs of different generations in the workforce. A generation is defined as a society-wide peer group which possesses a commonality of experiences. These common experiences result in members of the same generation sharing common attitudes and behaviors. Differences among generations can negatively affect the work environment, and, if not addressed, may create rifts in the workplace. Participants will spend time understanding how communication and motivation can differ among generations. Through class activities, participants will gain skills to work more effectively with members of different generations.

A “Cloud Physics Science Discovery Day” workshop will be held on Tuesday, September 27, 2016, in the FL1 EOL Atrium, to focus on activities at NCAR associated with Cloud Physics/Cloud Processes. Workshop presentations will be made by scientists at NCAR, with interests in the areas of Cloud Processes, Cloud Physics/Microphysics, Cloud Radiation, and Cloud Remote Sensing Measurements. The objectives of the meeting, limited to those at NCAR/UCAR, include:

1.   To learn what research is ongoing at NCAR in cloud microphysics and cloud dynamics,

2.   To explore the frontiers in this field as represented by NCAR research,

3.   To develop improved collaborations across divisions on cloud topics.

The workshop will comprise a set of talks and open discussions. The workshop is open to all NCAR employees. The agenda for the workshop is available at:

Join the UCAR Center for Science Education (SciEd) for our Spectacular Super Science Saturday Event! Mark your calendar for November 5th and come help us with this fun annual event.

Super Science Saturday is NCAR's largest public event and is designed to increase public science literacy by bringing kids and adults together to explore hands-on activities, think about new ideas, learn about science, and highlight the exciting scientific research happening in Boulder and the surrounding communities!

This year's theme is "Our Changing Climate".

UCAR/NCAR/UCP staff help to make the event fun, meaningful, and informative by greeting the public and providing general information, engaging the public in simple science education activities, or assisting our Science Wizards.

Please consider volunteering for one of the following shifts:

9:30 am – 1:00 pm

12:30 pm – 4:30 pm

Click on the link below to sign up to volunteer with us at this amazing event:
