ssr.control {assist} | R Documentation |
The values supplied in the function call replace the defaults and a list with all possible arguments is returned. The returned list is used as the `control' argument to the `ssr' function.
ssr.control(job=-1, tol=0.0, init=0.0, theta, prec=1e-06, maxit=30, tol.g=0.0, prec.g=1e-06, maxit.g=30)
job |
an integer representing the optimization method used to find the smoothing parameter. The options are job=-1: golden-section search on (limnla(1), limnla(2)); job=0: golden-section search with interval specified automatically; job >0: regular grid search on [limnla(1), limnla(2)] with #(grids) = job + 1. Default is -1. This is only applicable to smoothing spline model with a single smoothing parameter. |
tol |
tolerance for truncation used in `dsidr' or `dmudr'. Default is 0.0 which sets to square of machine precision. |
init |
init=0 means no initial values are provided for smoothing parameters theta; init=1 means initial values are provided for the theta. Default is 0. This option is only applicable to smoothing spline models with multiple smoothing parameters. |
theta |
If init=1, theta includes intial values for smoothing parameters. Default is NULL. This is only applicable to smoothing spline models with multiple smoothing parameters. |
prec |
precision requested for the minimum score value in `dmudr', where precision is the weaker of the absolute and relative precisions. Default is 1e-06. This is only applicable to smoothing spline models with multiple smoothing parameters. |
maxit |
maximum number of iterations allowed in `dmudr'. Default is 30. This is only applicable to smoothing spline model with multiple smoothing parameters. |
tol.g |
the tolerance for elements of w's in GRKPK. Default is 0.0 which means using the machine precision. This is only applicable to generalized spline smoothing. |
prec.g |
precision for stopping the iteration in GRKPK. Default is 1e-06. This is only applicale to generalized spline smoothing. |
maxit.g |
maximum number of iterations allowed for the iteration in GRKPACK. Default is 30. This is only applicale to generalized spline smoothing. |
