conflict_disbayes | R Documentation |
A test of the hypothesis that the direct data on a disease outcome give the same
information about that outcome as an indirect evidence synthesis obtained from a fitted disbayes
model. The outcome may be annual incidence, mortality, remission probabilities,
or prevalence.

A data frame with columns indicating age, gender and area.
p1
is a "one-sided" p-value for the null hypothesis that r_{obs}=r_{fit}
against
the alternative that r_{obs} > r_{fit}
,
p2
is the two-sided p-value for the null hypothesis that r_{obs}=r_{fit}
against
the alternative that r_{obs}
is not equal to r_{fit}
,
where r_{obs}
is the rate informed only by direct data, and r_{fit}
is the rate
informed by evidence synthesis. Therefore if the evidence synthesis excludes the
direct data, then these are interpreted as "conflict" p-values (see Presanis et al. 2013).
In each case, a small p-value favours the alternative hypothesis.
