|
data |
Matrix of observed data values. |
times |
Vector observation times for the data. |
pars |
Initial values of parameters to be estimated processes. |
beta |
Initial values of the contribution of lags for the delay. |
coefs |
Vector giving the current estimate of the coefficients in the spline. |
lik |
|
proc |
|
in.meth |
Inner optimization function currently one of |
control.in |
Control object for inner optimization function. |
basisvals |
Values of the collocation basis to be used. This should be a basis object from the fda package. |
fdobj0 |
A functional data object fitted with the history part of the data. |
This minimizes the objective function for DDE models defined by the addition of the lik
and proc
objectives with respect to the coefficients. A number of generic optimization routines can be used and some experimentation is recommended.
A list with elements
A matrix giving he optimized coefficients.
The results of the inner optimization function.
