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.

The Julia language has a unified interface to its plotting functionalities, supported by multiple backends such as plotly and pyplot (matplotlib). We will cover the fundamentals of Julia's plotting capability, and show the process of creating data visualization from select examples, including interactive and animated plots.

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…

** THIS WORKSHOP IS BEING RESCHEDULED TO MAY 24, 2021 ** The Hoffman2 Cluster is a powerful computational resource for the UCLA research community. This workshop is part III of a three-seminar series designed to introduce users to the Hoffman2 Cluster environment and to clarify the process of porting applications or using applications already available on the cluster. It also addresses how to port your workflow to the cluster and how to submit batch and run interactive applications. More Case…
