LagKernelWeight is an S4 class that implements a weighting function by
specification of a kernel function W and a scale parameter bw.
Wa kernel function
bwbandwidth
envAn environment to allow for slots which need to be accessable in a call-by-reference manner:
valuesA vector storing the weights; see the Details section.
It extends the class Weight and writes
$$W_N(x[k]) := W(x[k]/bw)$$
to values[k] [nested inside env] for k=1,...,length(x).
The points x where \(W\) is evaluated may be set on construction or updated when
evoking the method getValues.
Examples for implementations of kernels W can be found at:
