Description
A formal S4 class representation of Sparre Andersen's extension that
includes capital injections.
Details
The model is defined as follows:
X_(t) = u + ct + ∑_{k=1}^{N^{(+)}(t)} Y^{(+)}_k -
∑_{i=1}^{N^{(-)}(t)} Y^{(-)}_i
where u is the initial capital (initial_capital), c is the
premium rate (premium_rate), N^{(+)}(t) is the renewal process
of positive jumps (capital injections) defined by distribution of
interarrival times (capital_injection_interarrival_generator and
capital_injection_interarrival_parameters), Y^{(+)}_k are iid
capital injections' sizes (capital_injection_size_generator
and capital_injection_size_parameters), N^{(-)}(t) is the
renewal process of claims defined by distribution of interarrival times
(claim_interarrival_generator and
claim_interarrival_parameters), Y^{(-)}_i are iid claim sizes
(claim_size_generator and claim_size_parameters).
Objects of class can be created only by using the constructor
SparreAndersenCapitalInjections.
Slots
initial_capitala length one numeric non-negative vector specifying an
initial capital.
premium_ratea length one numeric non-negative vector specifying a
premium rate.
claim_interarrival_generatora function indicating the random
generator of claims' interarrival times.
claim_interarrival_parametersa named list containing parameters for
the random generator of claims' interarrival times.
claim_size_generatora function indicating the random generator of
claims' sizes.
claim_size_parametersa named list containing parameters for the
random generator of claims' sizes.
capital_injection_interarrival_generatora function indicating
the random generator of capital injections' interarrival times.
capital_injection_interarrival_parametersa named list containing
parameters for the random generator of capital injections' interarrival
times.
capital_injection_size_generatora function indicating the random
generator of capital injections' sizes.
capital_injection_size_parametersa named list containing parameters
for the random generator of capital injections' sizes.
