kern=arg (default=“epan”)

Kernel type: “epan” (Epanechnikov, default), “trngl” (Triangular), “unif” (Uniform), “gauss” (Normal–Gaussian), “bi” (Biweight–Quartic), “tri” (Triweight).

eval=arg (default=“data”)

Evalution points: observed data (“data”), grid of values (“grid”).

if “eval=grid” you must specify the grid values using “gmin=”, “gmax=” and “glen=”, or using “gvec=”.

gmin = arg

Estimation grid minimum (if “eval=grid”). Must be specified along with “gmax=” and “glen=”.

gmax = arg

Estimation grid maximum (if “eval=grid”). Must be specified along with “gmin=” and “glen=”.

glen = arg

Estimation grid length (if “eval=grid”). Must be specified along with “gmin=” and “gmax=”.

gvec = arg

Estimation grid points in a vector object (if “eval=grid”).

plyk = arg (default = 1)

Estimation polynomial degree for final stage.

auxk = arg (default = 2)

Estimation polynomial degree for pilot stage in excess of final stage.

p

Print results.
