Code for Estimating cutoff values for diagnostic tests with extreme value theory (Pugh, Fosdick, Nehring, Gallichotte, VandeWoude, and Wilson)
data-analysis.R: Estimates cutoffs for COVID-19 spike and RBD ELISA test data
fit-mixture-distributions.R: Fits mixture distributions to the COVID-19 spike and RBD ELISA test data, which are used in the simulation study
simulation.R: Runs a simulation study comparing the cutoff methods
