Prepares serosurvey for plotting — prepare_serosurvey_for

Adds seroprevalence values with corresponding binomial confidence interval

Usage

prepare_serosurvey_for_plotting(serosurvey, alpha = 0.05)

serosurvey

survey_year: Year in which the survey took place (only needed to plot time models)
age_min: Floor value of the average between age_min and age_max
age_max: The size of the sample
sample_size: Number of samples for each age group
n_seropositive: Number of positive samples for each age group

alpha

1 - alpha indicates the confidence level to be used

serosurvey with additional columns:

seroprev: Seroprevalence computed as the proportion of positive cases n_seropositive in the number of samples sample_size for each age group
seroprev_lower: Lower limit of the binomial confidence interval of seroprev
seroprev_upper: Upper limit of the binomial confidence interval of seroprev
