prob_seroprev_time_by_age.Rd

This function calculates the probabilities of seropositivity by age based on a time-varying FoI model. It takes into account the FoI and the rate of seroreversion.

Usage

prob_seroprev_time_by_age(foi, seroreversion_rate)

Arguments

foi

A dataframe containing the FoI values for different years. It should have two columns: 'year' and 'foi'.

seroreversion_rate

A non-negative numeric value representing the rate of seroreversion.

Value

A dataframe with columns 'age' and 'seropositivity'.
