knots {locfit} | R Documentation |
Extracts information, such as fitted values, influence functions
from a "locfit"
object.
knots(x, tr, what, delete.pv, ...)
x |
Fitted object from locfit() .
|
tr |
Back transformation. Default is the invers link function from the Locfit object. |
what |
What to return; default is c("x","coef","h","nlx") .
Allowed fields are x (fit points); coef (fitted values);
f1 (local slope); nlx (length of the weight diagram);
nlx1 (estimated derivative of nlx ); se (standard errors);
infl (influence function); infla (slope of influence function);
lik (maximixed local log-likelihood and local degrees of freedom);
h (bandwidth) and deg (degree of fit).
|
delete.pv |
If T , pseudo-vertices are deleted. |
... |
not used. |
A matrix with one row for each fit point. Columns correspond to
the specified what
vector; some fields contribute multiple columns.
