Another current obsession, tentatively placemarked. Discrete-state random fields/processes with a continuous index. In general I also assume they are non-lattice and simple, which terms I will define if I need them. For now, see DaVe03.

The most interesting class for me are the branching processes.

I’ve just spent 6 months thinking about nothing else, so I won’t write much here.

Questions:

- What is the most general point process that we can represent by a non-Homogeneous Poisson process? (This isn’t a research question, this is something I need to collate)

There is a comprehensive introduction in the 2 volume Daley and Jones epic. (DaVe03, DaVe08)

A curious thing is that much point process estimation theory concerns
estimating statistics from a single realisation of the point process.
But in fact you may have many point process realisations.
This is not news *per se*, just a new emphasis.

## Temporal point processes

Sometimes including spatiotemporal point processes, depending on mood.

In these, one has an arrow of time which simplifies things because you know that you “only need to consider the past of a process to understand its future”, which potentially simplifies many calculations about the conditional intensity processes; We consider only interactions from the past to the future, rather than some kind of mutual interaction.

In particular, for nice processes you can do fairly cheap likelihood calculations to estimate process parameters etc. I do a lot of this, for example, over at the branching processes notebook, and I have no use at the moment for other types of process, so I won’t say much about other cases for the moment.

See also change of time.

## Spatial point processes

Processes without an arrow of time arise naturally, say as processes where you observe only snaphosts of the dynamics, or where whatever dynamics that gave rise to the process being too slow to be considered as anything but static (forests).
