Update initial conditions and events for DiscreteTimeStateTransitionModel

In observations of a DiscreteTimeStateTransitionModel realisation, there may be uncertainty about the initial conditions and hence the number of events occurring in the early part of the timeseries. This MCMC kernel provides a means of updating these left-censored events.

Parameters:

• incidence_matrix (the state-transition graph incidence matrix)

• transition_index (the index of the transition in incidence_matrix to) – update

• max_timepoint (max timepoint up to which to propose moves)

• max_events (max number of events per unit/timepoint to move)

• events_varname (the name of the random variable holding the events) – timeseries in a NamedTuple supplied to both the init and step functions.

• initial_conditions_varname (the name of the random variable representing the) – initial conditions in a NamedTuple supplied to both the init and step functions.

• name (name of the kernel.)
