Seminars

Workshops for Spring, 2020

Introduction to ggplot2, Monday, April 27 from 1 to 4 p.m. via Zoom

Description: The ggplot2 package is a widely-used and well-supported system for creating eye-catching graphics in R. In this interactive workshop, you will learn the underlying grammar of graphics that forms the philosophical framework of ggplot2, giving you the power to create publication-quality figures intuitively. The workshop is interactive, in which attendees are encouraged to participate in R coding to create their own statistical graphics.

The notes for the workshop are here. This workshop will be hands-on. Attendees should have R and R Studio installed on their computers prior to the start of the workshop.

Attendance is restricted to researchers from the University of California. The information for the Zoom meeting will be sent the day before the workshop.

Introduction to Mplus 8, Monday, May 4 from 1 to 4 p.m. via Zoom

Description: Mplus is a powerful statistical package used for the analysis of latent variables. Among the kinds of analysis it can perform are exploratory factor analysis, confirmatory factor analysis, latent class analysis, latent growth curve modeling, structural equation modeling and multilevel modeling. The program can handle a combination of categorical and continuous variables and often permits missing data. It integrates these analyses into a single framework where you can combine techniques like growth curve modeling and latent class analysis to ask unique questions, such as “Are there latent classes among the growth trajectories?”. Mplus runs under Windows. This workshop is designed for people who are just getting started using Mplus to orient them to the nuts and bolts of using this package. These notes are the scripts for the workshop. The notes are not meant to be a Mplus textbook or substitute for the reference manual.

Attendance is restricted to researchers from the University of California. The information for the Zoom meeting will be sent the day before the workshop.

R Data Management, Monday, May 11 from 1 to 4 p.m. via Zoom

Description: This workshop introduces R packages and functions that help users import, transform and manage their data in preparation for analysis. The seminar focuses on the “tidy data” philosophy encouraged y the “tidyverse” collection of R packages, but draws on other packages for useful functions as needed. Topics include data import, transforming variables, string functions, missing data, merging datasets, reshaping data, grouped data processing, and looping.

Attendance is restricted to researchers from the University of California. The information for the Zoom meeting will be sent the day before the workshop.

A Practical Introduction to Exploratory Factor Analysis (EFA) in SPSS, Monday, May 18 from 1 to 4 p.m. via Zoom

Description: This workshop will give a practical overview of exploratory (EFA) in SPSS. Topics to be covered include factor extraction, principal components analysis, estimation methods, factor rotation, refining the factor structure, and generating factor scores for subsequent analyses.

The notes for the workshop are here. This workshop will not be hands-on.

Attendance is restricted to researchers from the University of California. The information for the Zoom meeting will be sent the day before the workshop.
