how to save PDF of kernel density?

Hi all,

I have a project that requires me to compute a pdf of a kernel density hundreds of thousands (millions) of times and I wanted to see if I can save a kernel density pdf so that my code doesn't have to load the observations to which the kernel density is fitted. Right now the only way I know how to evaluate a kernel density pdf requires my machine to work with the vector of observations each and every time to evaluate the kernel pdf.

How would you expect that the kernel density should be represented ?

I think if you read the documentation on how the kernel density pdf is evaluated, there is no other way than to recalculate it at each point x for which it is called.
