The UCLA Department of Statistics and the Center for Social Statistics presents: Programming data science with R & the tidyverse Tidy evaluation is a new framework for non-standard evaluation that will be used throughout tidyverse. In this talk, I'll introduce you to the problem that tidy eval solves, illustrated with examples of the various approaches used in R. I'll then explain the most important components so that you can start writing your own functions instead of copying and pasting tidyr…

Workshop: Useful R 4 Stata Users Brown Bag

October 13, 2017 @ 12:00 pm - 1:00 pm

Instructor: Michael Tzen, CCPR UCLA   Abstract: This workshop is a brown bag forum. Participants are encouraged to bring in tangible questions they wish to explore using R. To serve as a background road map, the instructor will provide an abbreviated sample of what he thinks are the most useful features of R. However, the goal is to have participants ask questions that the collective group can figure out using R. Any R question is fair game, for example: questions…

The UCLA Departments of Epidemiology, Biostatistics, Statistics and the Center for Social Statistics presents: Causal Methods in Epidemiology: Where has it got us and what can we expect in the future? The principal focus of Dr. Robins’ research has been the development of analytic methods appropriate for drawing causal inferences from complex observational and randomized studies with time-varying exposures or treatments. The new methods are to a large extent based on the estimation of the parameters of a new class…

The Center for Social Statistics Presents: Predicting the Evolution of Intrastate Conflict: Evidence from Nigeria The endogenous nature of civil conflict has limited scholars' abilities to draw clear inferences about the drivers of conflict evolution. We argue that three primary features characterize the complexity of intrastate conflict: (1) the interdependent relationships of conflict between actors; (2) the impact of armed groups on violence as they enter or exit the conflict network; and (3) the ability of civilians to influence the…

Instructors: Michael Tzen, CCPR UCLA Andy Lin, IDRE UCLA   Abstract: In this workshop, attendees will learn how to analyze survey data while accounting for its complex survey design. Using both the R and Stata software packages, we will demonstrate how to specify the survey design, impute any missing data, and analyze the survey outcomes of interest. We will discuss how our downstream "analysis" steps are related to initial operational "design" choices made by the survey data provider.   Note:…
