Hi Erin, Depending on what you're trying to do, you may want to look into point pattern analysis, particularly on linear networks (lots of research on how to conduct kernel density estimations with traffic accident data) See spatial analysis along networks (Okabe and Sugihara, 2012) and chapter 17 of spatial point patterns methodology and applications with R (Baddeley et al. 2016) for introductions. Hope that helps. Kind regards, Joseph Lewis

Hi again everyone: Sorry for the unclear question. Typically, I have data that is at say, 8 locations and collected every hour. So spatial and/or spatial-temporal kriging works fine. In this case, I am dealing with traffic accident data. So it can be at "any" location and at any time. I had the (probably incorrect) impression that kriging may not work in that setting. Any info much appreciated. Thanks for your understanding.

Howdy, Danie Kriege [d?ni? ?kri??] <https://en.wikipedia.org/wiki/Help:IPA/Afrikaans> was a mining

I find it very hard to believe there is a practicing engineer who thinks that you can find a gold mine only if you have collected data in a
regular
grid (if that is what you mean with ?regular data"). Indeed, his methods can be used for usual prospecting data ? which typically is irregular or not in a regular grid. Cheers, J.

99.9%
sure that there is not, but just thought I would double check. Thanks so much for your help! Happy Holidays! Sincerely, Erin -- Erin Hodgess, PhD mailto: erinm.hodgess at gmail.com [[alternative HTML version deleted]]
