Hi,
I have two separate questions relating to the KernSmooth package. I am
using the dpik function from the KernSmooth package and receive the error
Warning message:
In kappam * Gcounts :
longer object length is not a multiple of shorter object length
I saw an earlier post , but the issue was using the bkde fxn and the
person appeared to be using too small of a bandwidth. However,
dpik returns a bandwidth and therefore I am not sure why I am getting this
error. If I use dpik and specify scalest to be "stdev" then the fxn works.
Secondly, I am using the bkde function and when I put in a vector of data
the function computes some bandwidth to use as it then proceeds to return x
and y vectors. I do not see in the documentation the process by which this
bandwidth is computed. It does not appear to match the bandwidth (or even
be remotely close, it is an order of magnitude different) when using the
dpik function (with scalest = "stdev"). If someone could tell me how it
calculates the bandwidth which the function uses I would appreciate it.
Thank you in advance.
