Fig. 2From: covidscreen: a web app and R Package for assessing asymptomatic COVID-19 testing strategiesBackend Computation Graph. Inputs are gathered and validated prior to use. If validation fails, no further computation occurs. Conditional distributions of each variable are created using these inputs, then joined and multiplied sequentially to build up an unconditional distribution. This distribution is summarized for each output, and results are passed back to the user interface. This process occurs after each change to user input, but only the necessary components are updated each timeBack to article page
