par.vec |
vector with model parameter values |
par.names |
parameter names, character vector equal in length to par |
par.restr |
parameter equality restrictions, data.frame; par.vec and par.restr have to exhaust the model parameter set together. |
N.factors |
integer, number of SV factors |

model_Likelihood
if for.estimation==TRUE
: log-likelihood value (NOT negative of...), else: list with filtering results
model_translateParameters
list
with fields P
and Q
, input for all ODE calling functions.
model_makeDefaultParameterStructures
returns data.frame
par.restr
and character
vector par.names
model_fellerConditionCheck
list with two logical vectors reporting whether the Feller conditions are satisfied
model_Likelihood_extraNoise
list
with fields P
and Q
, input for all ODE calling functions.
model_wrapLikelihood_extraNoise
wraps the likelihood function with extra noise so that it only accepts a parameter vector argument – use this for optimizers that do not allow passing extra arguments to the optimised function.
model_Likelihood_portfolio_extraNoise
list
with fields P
and Q
, input for all ODE calling functions.
model_wrapLikelihood_portfolio
wraps the likelihood function so that it only accepts a parameter vector argument – use this for optimizers that do not allow passing extra arguments to the optimised function.
model_Likelihood_affineContracts
list
with fields P
and Q
, input for all ODE calling functions.
model_wrapLikelihood_affineContract
wraps the likelihood function so that it only accepts a parameter vector argument – use this for optimizers that do not allow passing extra arguments to the optimised function.
