I'd like to thank all of you for replying to my post. You helped a
lot. Now I'm trying to find access to S-PLUS software somewhere in my
country... Anyway, the summary of all answers can be found in three
e-mails I pasted here:
>From Joël Mossong <[log in to unmask]>
> Dear Srdjan,
>
> Not sure if this is of much help, but I remember there is a good book by B.
> Silverman at the University of Bristol on density estimation using kernels.
> That might give you a clue on how to do it, respectively software for it.

> Best wishes,
> Joël Mossong
>From Adrian Bowman <[log in to unmask]>
> If you have access to S-Plus then you might find it useful.
> Adelchi Azzalini and I have developed a smoothing library
> for S-Plus and this contains a 2-d density contouring procedure
> which you might find helpful. The library is available

> Adrian Bowman
>From Noritoshi Tamura <[log in to unmask]>
