kernel.constants {gplm} | R Documentation |
Calculates several constants of a (product) kernel function.
kernel.constants(kernel = "biweight", d = 1, product = TRUE)
kernel |
text string, see |
d |
integer (dimension of the kernel) |
product |
(if d>1) product or spherical kernel |
The constants which are calculated are the second moment, the square norm and the canonical bandwidth of the kernel (only the two latter terms depend on the dimension d).
List with components:
m2 |
second moment |
c2 |
square norm |
d0 |
canonical bandwidth |
