# Online and Free Software Tools

## 01 shinySSVS

shinySSVS is an online application for performing stochastic search variable selection (SSVS) and visualizing the results. SSVS is a Bayesian variable selection method that can be used to estimate the probability that each of a set of candidate predictors be included in the model. The shiny application accepts a variety of data formats and includes functionality for continuous or binary outcome variables.

## 02 SSVS R package

SSVS is an R package available on CRAN for implementing stochastic search variable selection and visualizing the results. This package includes the same functionality as the shinySSVS web application, however native R users may prefer to call the functions from R. This can be useful for reproducing results from lots of models or running simulation studies.

## 03 ShinyDLRs

ShinyDLRs is an online application for performing ROC analysis to determine optimal diagnostic likelihood ratios (DLRs). DLRs are an important tool for evidence-based assessment.
