In jimhester/surveillance: Temporal and Spatio-Temporal Modeling and Monitoring of Epidemic Phenomena

Description

The special function cox marks terms in formulae of the functions twinSIR and simEpidata as endemic components, i.e. variables acting multiplicatively on the baseline infection intensity.

Technically, this function is implemented as function(x) {x} and defined as “special” in terms.formula.
