EvalTest - Tools for Evaluating Diagnostic Test Performance
Evaluates diagnostic test performance using data from laboratory or diagnostic research. It includes functions to compute common performance indicators along with their confidence intervals, and offers an interactive 'shiny' application for comprehensive analysis including ROC curve visualization and related metrics. It supports both binary and continuous test variables. It allows users to compute key performance indicators and visualize Receiver Operating Characteristic (ROC) curves, determine optimal cut-off thresholds, display confusion matrix, and export publication-ready plot. It aims to facilitate the application of statistical methods in diagnostic test evaluation by healthcare professionals. Methodological details and references for the computation of performance indicators are provided in the package vignette.

The 'EpiSimR' package provides an interactive 'shiny' app based on deterministic compartmental mathematical modeling for simulating and visualizing the dynamics of epidemic and endemic disease spread. It allows users to explore various intervention strategies, including vaccination and isolation, by adjusting key epidemiological parameters. The methodology follows the approach described by Brauer (2008) <doi:10.1007/978-3-540-78911-6_2>. Thanks to 'shiny' package.
