A measure of how past behaviour influences the adherent and non-adherent behaviour of individuals is in the n-th round of treatment, ωn ≡ βnn−1 + γnn−1 − 1, which was introduced in Eq (13).

This value is given for each age group and sex inferred from the TUMIKIA project dataset and is computed using the maximum likelihood values for the conditional probabilities. The uncertainties quoted with each value correspond to the standard deviation of ωn in each case.
