Computes the scaled tansmission assortativity coefficient, see function gamma2delta.
Usage
get_delta(from, to, f, alpha = 0.05)
Arguments
- from
A vector of infectors.
- to
A vector of infectees.
- f
A named numeric value representing the prevalence of each group in the population or directly the group sizes.
- alpha
The significance level for the confidence interval.
Value
A data frame with the estimated delta, lower and upper confidence limits for each group.
Examples
from <- c("A", "A", NA, "C", "C", "C")
to <- c("A", "B", "B", "C", "C", "C")
f <- c(A = 0.3, B = 0.2, C = 0.5)
get_delta(from, to, f, alpha = 0.05)
