Continuous-time processes with attraction?

    I'm trying to find a good model, and I wanted to find a process that fits. The Poisson process almost fits, but unfortunately the independence assumption is too strong for my data. Is there a similar process that has a parameter (or several) that allow for points to attract or repel others, like zeta zeros?

    I've never been good with statistics, so there could be a very simple process I've overlooked, I don't know.

    Negative binomial distribution?
    The distribution is described by 2 parameters.
    One could be considered a "dispersion" parameter;
    a degree of "clumping" in the population?
    Maybe it could provide a knob for dialing up or down the degree of attraction or repulsion.

    Oh, cool. This looks good -- I'll have to try it with my population to see how well it can model it.

    Thanks!
