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)a list with components for each of the possible arguments.
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 the number of grids = job + 1. Default is -1. This is only applicable to smoothing spline model with a single smoothing parameter.
tolerance for truncation used in `dsidr' or `dmudr'. Default is 0.0 which sets to square of machine precision.
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.
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.
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.
maximum number of iterations allowed in `dmudr'. Default is 30. This is only applicable to smoothing spline model with multiple smoothing parameters.
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.
precision for stopping the iteration in GRKPK. Default is 1e-06. This is only applicale to generalized spline smoothing.
maximum number of iterations allowed for the iteration in GRKPACK. Default is 30. This is only applicale to generalized spline smoothing.
