findstartparamyields: Find Globally Optimal Start Parameters
Description
Start parameter search routine for term structure estimation based on a yield data set.
The algorithm searches for the parameters over a grid spanned over tau1 (tau2).
Usage
findstartparamyields(y,m, method, tauconstr,
control = list(), outer.iterations = 30, outer.eps = 1e-04)
Arguments
method
type of spot rate function
tauconstr
tau parameter constraints
control
solver control parameters, for details see optim
Value
"spsearch", which
includes the startparameters and details concerning the optimization.
Details
Used as internal helper function
