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

Hi Erin,

I'm not sure what you mean by "irregular data." There's no requirement
that points be on a grid, and that's the only thing I can think of,
but I'm not sure how you'd get the idea that that was required given
the existence of the basic tutorials using the meuse dataset.

So, please expand on your question.

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.

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
