Re: [R] Implementing Silverman's Negative Reflection

Thank you for the "obvious" help - I already saw this thread. But I thought this described the "standard" reflection method (which I managed to implement). In my case, I want to achieve a NEGATIVE reflection which is *not* the same as the method where you simply reflect the data, estimate the de

Hi! I'm trying to implement in R in an easy way the negative reflection method described in Silverman (1986) on p.31, ie I have a non-negative dataset and would like to estimate the density by applying a reflection method where the reflected points have weight -1. I thought there should be a way to
