These functions can be used to change some estimator options.
setestimator(x, estimator)setoptimizer(x, optimizer = c("default","nlminb","ucminf","cpp_L-BFGS-B",
"cpp_BFGS","cpp_CG","cpp_SANN","cpp_Nelder-Mead"))
usecpp(x, use = TRUE)
A psychonetrics model.
A string indicating the estimator to be used
The optimizer to be used. Can be one of "nlminb" (the default R nlminb function), "ucminf" (from the optimr package), and C++ based optimizers "cpp_L-BFGS-B", "cpp_BFGS", "cpp_CG", "cpp_SANN", and "cpp_Nelder-Mead". The C++ optimizers are faster but slightly less stable. Defaults to "nlminb".
Logical indicating if C++ should be used (currently only used in FIML)
An object of the class psychonetrics (psychonetrics-class)
