Functions in inctools (1.0.15)

frrcal

Estimate False-Recent Rate

excalibdata

The dataset `excalibdata.Rdata` contains example data from an evaluation of an assay measuring recency of infection. At an assay result of <10, the specimen is considered to be recently infected. It further contains viral load data, which is commonly used to reduce false recency. For example, when recency is defined as assay result <10 and viral load > 1000, the FRR is substantially lower (but the MDRI is also reduced).
