A use case that has been discussed extensively during the development of the package is related to Human Papillomavirus (HPV). We've explored the use of age-varying forward random walk models with seroreversion to estimate the FOI in real-life scenarios. To exemplify this, consider the following simulated serosurvey:
The options we've been using to model sexual debut from 15 years old on are similar to (custom FOI indexation can also be used):
seromodel <- fit_seromodel(
model_type = "age",
serosurvey = serosurvey,
foi_prior = sf_normal(0, 1e-5), # set first FOI to zero
foi_index = get_foi_index(serosurvey, 15),
is_seroreversion = TRUE
)
Yielding the following results:
By specifying the seroreversion rate prior by means of the seroreversion_prior parameter is possible as long as the selection is justified.
We want to add a use case to the Real-Life Use Cases For Serofoi article (file). For this, we need to select and add a real-case dataset to the package and redact the use case in a similar manner to the others. @zmcucunuba, please branch from dev to work on this.
