Michael Tzen May 21, 2015 2:00pm-5:00pm 2400 Public Affairs Building An increasing number of longitudinal datasets are being made available. The longitudinal nature of the dataset may be represented as a hierarchy of stages, say, measurements across time nested within an individual. We’ll discuss how hierarchical models account for the nested structures and how Generalized […]

Users write statistical models in a high-level statistical language. The default Bayesian inference algorithm is the no-U-turn sampler (NUTS), an auto-tuned version of Hamiltonian […]
The All-California Labor Economics Conference (ACLEC) brings together the top labor economists in California annually to present recent research. This year’s conference will be hosted by UCLA on Thursday, September 17 and Friday, September 18. Leah Boustan (Economics) and Sarah Reber (Public Policy) are co-organizing. The local planning committee consists of Leah Boustan, Sarah Reber, […]
Researchers go through fundamental steps in a data analysis project. This workshop highlights key steps in a data analyst's workflow and encourages transparency in each of the steps. Throughout this workshop, we go through hands on exercises that integrate: a transparency engine, obtaining federal API data, producing useful intermediate data structures, and sharing analysis results. […]
Presented By: Mark S. Handcock (Professor, Statistics) Jeffrey B. Lewis (Professor, Political Science) Marc A. Suchard (Professor, Biomathematics, Biostatistics and Human Genetics) Reproducibility is one of the main principles of the scientific method. This panel of scholars will discuss issues in the importance of replication of statistical results. Increasing attention is being paid to […]
CCPR is hosting the annual NBER Cohort Studies meeting which brings together researchers from different fields interested in aging related issues or in methodologies applicable to aging and has set the seeds for synergistic relationships between economists, sociologists, demographers, psychologists, epidemiologists, and MDs.

About: This presentation will briefly go through the initial application process, amendments and continuing reviews with a focus on working with the IRB and the understandable but common mistakes in completing the various applications. It will include information on the process of obtaining and renewing CITI training for both PI’s and Faculty Sponsors.
Content: Geographically referenced data sets are becoming increasingly common.
In spatial analysis of demographic data, three common spatial indices are used: points, lines, and polygons. Through interspersed hands on exercises, we will: obtain, shape, and visualize demographic data over space. We will briefly discuss the motivation for incorporating geographic association into downstream models.
Below is an example of what we will produce with
1) Obtain GPS locations of In-N-Out's obtained from the Google Radar API
2) Compute their generated Voronoi Tesselation to address spatial competition
3) Aggregate Census 2010 tract-level population counts into these competing geographies
No background knowledge of will be required. The exercises are introductory. We will also highlight alternative software tools to achieve similar goals, such as GrassGIS and Stata

"Innovative Sampling Approaches for Hard to Reach Populations: Design of a National Probability Study of Lesbians, Gay Men, Bisexuals, and Transgender Peoples and Network Sampling of Hard to Reach Populations"
Speakers:
Ilan H. Meyer, Williams Distinguished Senior Scholar for Public Policy at the Williams Institute
Mark S. Handcock, Professor of Statistics at UCLA and Director of the Center for Social Statistics
Description:
Come for the exciting seminar then stay for the free lunch and discussion. A seminar led by Ilan H. Meyer followed immediately by a Brown Bag Lunch led by Mark S. Handcock.
Dr. Meyer is Principal Investigator of the Generations and TransPop Surveys. Generations is a survey of a nationally representative sample of 3 generations of lesbians, gay men, and bisexuals. TransPop is the first national probability sample survey of transgender individuals in the United States. Both studies attempt to obtain large nationally representative samples of hard to reach populations. Dr. Meyer will review sampling issues with LGBT populations and speak on the importance of measuring population health of LGBTs and the underlying aspects in designing a national probability survey.
From a contrasting perspective, the field of Survey Methodology is facing many challenges. The general trend of declining response rates is making it harder for survey researchers to reach their intended population of interest using classical survey sampling methods.
In the followup Brown Bag Lunch, led by Mark S. Handcock, participants will discuss statistical challenges and approaches to sampling hard to reach populations. Transgenders, for example, are a rare and stigmatized population. If the transgender community exhibits networked social behavior, then network sampling methods may be useful approaches that compliment classical survey methods.
Participants are encouraged to speak on ideas of statistical methods for surveys.
Content: Researchers go through fundamental steps in a data analysis project. This workshop highlights key steps in a data analyst's workflow and encourages transparency in each of the steps. Throughout this workshop, we go through hands on exercises that integrate: a transparency engine, obtaining federal API data, producing useful intermediate data structures, and sharing analysis results. We will use Jupyter notebook for literate coding and if time allows demonstrate the Rstudio environment for reproducible development.
