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
