For a given combination of prevalence, sensitivity and specificity this gives
the critical threshold at which true prevalence equals apparent prevalence
Usage
optimal_performance(p = NULL, sens = NULL, spec = NULL)
Arguments
- p
the prevalence or apparent prevalence
- sens
the sensitivity of the test
- spec
the specificity of the test
Value
the combination of sensitivity and specificity where apparent prevalence equals true prevalence
Examples
optimal_performance(p=0.1, sens=0.75)
#> $p
#> [1] 0.1
#>
#> $sens
#> [1] 0.75
#>
#> $spec
#> [1] 0.9722256
#>
optimal_performance(p=0.005, spec=0.9975)
#> $p
#> [1] 0.005
#>
#> $sens
#> [1] 0.5024969
#>
#> $spec
#> [1] 0.9975
