Kernel estimation

Palpanas et al. 2003 Distributed deviation detection in sensor networks (p79)

• Assume a local distribution
• Scream if you do not find it.

But how to assume the local kernel function?

• There are so many.
• Palpanas et al. comment that the actual kernel does not matter. (p79). 
• This is not quite correct. Schneid reports that Wand & Jones reports that the choice of kernel is not as important as choice of bandwidth  (if the sampling bandwidth is high enough, then anything is nearly good enough).
