註釋This tool describes how to use a menu-driven Shiny application (app) based on the Toolkit for Weighting and Analysis of Nonequivalent Groups (TWANG) R package. The TWANG package was first developed in 2004 by RAND Corporation researchers for the R statistical computing language and environment. The RAND team has now developed interactive, menu-driven apps of the original TWANG functions using the Shiny software development package. Shiny is an R package that makes it easy to build interactive web apps straight from R. This tutorial provides an introduction on how to use our TWANG Shiny app for time-varying treatments. The tutorial demonstrates use of the Shiny app through an illustrative example and explains key inputs and outputs of the TWANG Shiny app for time-varying treatments. More specifically, it provides an introduction about how to use the TWANG Shiny app for time-varying treatments to estimate the inverse probability of treatment weights (IPTW) for time-varying treatments when using observational data and to calculate treatment effect estimates using those IPTW.
