Kriging question, please

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.

Sincerely,
Erin

Howdy,

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

engineer.

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.

Hello!

Is there a method for Kriging for irregular data, please?  I?m about

99.9%

sure that there is not, but just thought I would double check.

Thanks so much for your help!

Happy Holidays!

Sincerely,
Erin
