In SVA-SE/freedom: Demonstration of Disease Freedom (DDF)

hse_infinite

Description

Herd Sensitivity calculated with the assumption of an infinite population

Usage

hse_infinite(id, n_tested, test_Se, dp)

Arguments

id	The herdid
n_tested	The number tested in each URG
test_Se	The sensitivity of the test. This may have length == 1 if all URG and all herds have the same test_Se. It may also have length(test_Se) == length(n_tested).
dp	The design prevalence (dp) could be length(dp) == 1 if all URG and herds have the same dp. It could alternatively be length(dp) == length(n_tested) if diff

Details

Calculate the Herd sensitivity when multiple samples from individual units within the herd. The function does not use the population size to adjust the estimate. This is consistent with the assumption of an infinite population size and is generally used when less than 10

Value

A data.frame. A dataframe is returned with 2 columns: "id" and HSe

Examples

df <- data.frame(id = seq(1:20),
                 n_tested = rpois(20, 5),
                 test_Se = 0.3,
                 dp = 0.05)

## Calculate the herd level sensitivity for each of these herds given
## the assumption that the herds have an infinite size.
hse_infinite(df$id,
             df$n_tested,
             df$test_Se,
             df$dp)
