Confirmatory Factor Analysis (CFA) in R with lavaan

May 17, 2021 @ 1:00 pm - 4:00 pm
Zoom

Zoom registration required: https://ucla.zoom.us/meeting/register/tJwkcuiqrjovGdFdq0u6EebmpiiX_KW00ohH This workshop will cover basic concepts of confirmatory factor analysis by introducing the CFA model and looking at examples of a one-factor, two-factor and second-order CFA. Concepts such as model identification, standardized solutions, and model fit statistics such as the chi-square statistic, CFI, TLI and RMSEA will be covered. The focus is on learning the CFA model and how to implement and interpret the output in R’s lavaan package.

Introduction to Virtual Machines and Containers

May 20, 2021 @ 10:00 am - 12:00 pm
Zoom

A virtual machine is an isolated operating system environment running on top of the host computer’s original operating system. This hypervisor-based technology enables us to run one or multiple operating systems on the same host computer (e.g. a Linux virtual machine on top of a Windows host computer). However, a virtual machine can be resource-heavy to the host computer. In recent years, the container technology has emerged as a lightweight alternative to the virtual machine, also providing an isolated software…
