Simulated one-titre antibody data

A simulated dataset containing 5000 independent observations on antibody titres and the corresponding infection status. The data was simulated to resemble real influenza infection and haemagglutinin titre data.

one_titre_data

Format

A data frame with 5000 observations and 2 variables:

logHI: haemagglutinin-inhibiting (HI) titre. True simulated titre on a log scale.
status: influenza infection status. 1 - infected. 0 - not infected

Model

The model behind the simulation was

$\lambda * (1 - f(\beta_0 + \beta_1 * HI))$

Where

$f$ - Inverse logit function
$\lambda$ = 0.5
$\beta_0$ = -5
$\beta_1$ = 2
