select.knots R Documentation
Knots selection for P-spline smoothing
Description
Construct knots from either quantiles of observed time points or
equally-spaced time points.
Usage
select.knots(t,knots=10,p=3,option="equally-spaced")
Arguments
t
Observed time points.
knots
Number of interior knots.
p
Degrees of B-splines to be used.
option
Default "equally-spaced": equally-spaced time points in the range of t; if "quantile",
then quantiles of t.
Details
The number of knots in the output will be knot plus 2 times p; and
the B-spline basis matrix constructed from this vector of knots with degrees p
will be knots plus p.
Value
A vector of knots
