kernel, ksdensity, force zero mean

Hi there,

I would like to estimate a kernel density based on a sample. However, I want to force the expectation of the obtained density estimate to be zero.

Any information for any piece of matlab code or even any theory about known approaches would be great. Thanx in advance for any answers!

I am not sure why you want to force the density to zero, but the Statistics toolbox has a built in ksdensity function.

doc ksdensity

Maybe this will help get you started.

Apologies if this was something you were already aware of.
