Run the example using:

birch sample \
  --model SIRModel \
  --input-file input/russian_influenza.json \
  --output-file output/russian_influenza.json \
  --ncheckpoints 14 \
  --nparticles 100 \
  --nsamples 10

The data set is of an outbreak of Russian influenza at a boy's boarding school in northern England (Anonymous, 1978). The model on which this is based is described in Murray et. al. (2018).
