Additional file 1 of Mitigation of biases in estimating hazard ratios under non-sensitive and non-specific observation of outcomes–applications to influenza vaccine effectiveness

Additional file 1. R script. Description of data: The file provides four R functions and a working example (at the end of the script) allowing the realisation of the weighted partial likelihood approach and probabilistic deletion of false-positive events. sirdata() returns a piece-wise constant hazard mimicking the force of infection in a Susceptible-Infected-Removed epidemic. simdata() simulates time-to-event data and estdata() estimates the vaccine effectiveness and its standard error as described in the main text. outdata() combines the data simulation and estimation steps and returns the performance measures presented in the manuscript.
