# Predictive value

A combination of [PPV (Positive Predictive Value)](https://www.psyctc.org/psyctc/glossary2/ppv-positive-predictive-value/) and [NPV (Negative Predictive Value)](https://www.psyctc.org/psyctc/glossary2/npv-negative-predictive-value/) of a screening design. See details in [screening](https://www.psyctc.org/psyctc/glossary2/screening/) and the [shiny app](https://shiny.psyctc.org/apps/Screening/) that allows you to get the NPV and PPV for any screening measure given the sensitivity and specificity of the measure and prevalence of the problem.
