What the Heck is a Variogram?

[@pablonapan4698]

The best geostatistics explanation on youtube. Thank you !

[@bojanblagojevic5759]

Jesus Christ what a difference between this explanation and what our professor should us. 😱😱😱 This video is awesome! So many things are clear now to me. 🙌🙌🙌

[@juliosergio00]

Excellent! Finally I have come to a site where I begin to understand this matter of the variograms

[@ghazevedo]

Great video, unfortunately I couldn't find the next video on variogram.

[@emmanuelm.k2474]

Wow, this is a memorable class. I am falling in love with spatial statistics. Keep up the good work

[@kilimamambo7030]

Thank you for such exemplary and clear explanations of the variogram and other concepts 🙌!

[@drewfrench8784]

I have to thank you deeplt for this clear explanation. Im only halfway through but this is finally allowing me to understand geostatistics in a way that classes haven't.

[@MyLab87]

Very interesting and well organized presentation and teacher. Really I benefited from this video. Many thanks!

[@sergiovr3]

excellent class you are a great teacher. I had trouble understanding these concepts and books didn't help. saludos desde Perú

[@neo78598]

Fantastic video! Very clear, comparing with my sleepy "docents" at the uni, til today I finally understood!Thank you!

[@NavigatEric]

Excellent video. Very clear speaking voice and thoroughly explained. Highly professional. Thank you, it helped a lot. Eagerly looking forward to the next series.

[@ManishTomar83]

Very nicely explained,Simply loved the style of presentation in a crisp and clear voice.Waiting eagerly for next videos upload.

[@joystick396]

You’ve perfectly described my entire semester in geostatistics thank you!!

[@blackwhite7134]

This explanation is so good that at some point I just knew you hold a PhD, which you do. Thanks a lot!

[@oOOpIIIqOOo]

Edward Isaaks, you're a genius. Great explanation, thank you very much.

[@JaimeBayes]

Thanks Edward, I finally understood this important concept, because of you!

[@MyIndia2100]

You are a great teacher. Love ur teaching

[@CoryKiser1991]

this is awesome, i sometimes have to supervise drilling core samples, this will come in handy determining how many holes to drill and how close

[@brady8714]

Great video, excellent introduction. Really appreciate you putting this together.

[@Summer-zy2yc]

Thank you so much!!!! It's absolutely terrific teaching about Variogram!! Cleared all my questions!! Very easy to understand. Best Ever!

[@pateto777]

Great explanation! I liked the use of geometry for the semivariogram concept, thanks!

[@amt466]

Excellent explanation ... I had been struggling for more than one year to understand the difference between correlogram and semi-variogram ... I also read your book "An Introduction to Applied Geostatistics" which was somewhat helpful ... but I admit the mistake on my part that reading books make me weary ... Anyhow I was unable to fully understand the concepts, until I stumbled upon this video. Many Thanks Dr. Isaaks!

[@kyvacipes]

Highly professional and fascinating explanation! Thank you, sir.

[@hugoraphaelcastro]

Fantatisc! Very clear!

[@dramandalee9679]

Great video, easy to interpret, looking forward to next two lectures. Thank you .

[@uzzalorpheus55]

Awesome Explanation. Thank you. Please share the rest of the videos.

[@goldhunter06]

Wow, excellent video presentation. Thank you.

[@amirch8818]

Great explanation, thanks!

[@CaPro89]

Many thanks for the vid. It was very helpful! Could you upload the other parts too?

[@ShaibalAhmed]

How powerful can the internet be? Dear Mr. Edward Isaaks, thank you for your efforts.

[@mahadeibnsalam6735]

Great content! Loved it!

[@konosh93]

Thank you for uploading this great video, looking forward for more,

[@ahmedaql502]

Eduard, that's a fantastic work!

Very good explanation! Thanks for your vid.

[@karimkarim4824]

Many thanks for this great video. But i can't find the next 2 videos (Calculating directional sample variograms & Modeling directional sample variograms).

[@alikoleiny3325]

I also can not find the next 2 videos.

[@ainulmardhiah1631]

such a great explanation! thanks so much!!

[@ondeonde2059]

thanks a lot. i was having a problem understanding the matter and this helps! xoxo

[@valhondo3]

Really appreciate the explanation, how can I find the other two videos?

[@gilesashearing]

My Masters looks at sediment and rivers so your video was very pertinent. Your explanation is fantastic. Thank you very much.

[@carloscuartas3391]

I like a lot this explanation. Thank you.

[@paulwellington614]

Good video. Could you please upload the other videos?

[@nekonihonjin]

Excelent explanation, thank you!

[@RockWhisperer577]

Awesome video

[@draknagar]

Beautiful style of explaining a segment of statistics, which is surprisingly made 'A mother of complexity' and people want to stay away from it. :)

[@fabioramilli8863]

I wish I had seen this beautiful resume earlier...

[@RenéFrijhoff]

Fantastic video. Thank you so much? Only thing that bugs me a bit is that the statistics don't add up with the %cg given in the two profiles at the beginning of the video. Am I missing something?

[@J4NFK]

I have the same issue with the video!

[@a.ibrahim2560]

Sir i'm terribly sorry. Im downloading your ebook which i get free from internet. I dont mean to steal from you, you are a gold standard in explaining elaborate theories. For your payment i can only pray that you have a good and happy long life, sir

[@woodya3380]

Amazing video. Thanks a lot

[@bergamobobson9649]

Excellent

[@ProfBoggs]

Is spatial continuity essentially the same things as positive spatial autocorrelation?

[@Tupapirico2011]

Excellent!

[@kimmusak1611]

Very easy and informative .. where is the 2nd video?

[@nelsonfractal]

Thanks very much.

[@kevindenelsbeck7444]

Thanks, that was terrific!

[@LA30310080]

You probably don’t realize but this is the great Isaaks who wrote with Srivastava An Introduction to Applied Geostatistics. Thank you very much

[@JoshCaiLovzu]

Sir I really appreciate this lecture. Immensely helpful and clear! However I'm just wondering if I used the correct method to calculate average and standard deviation of Lag 1 and Lag 2 of Stream 1 -- my averages and SD differ a bit from yours. My Steam 1 Lag 1 Mean(tail) = 0.913846, Mean(head) = 0.936923, SD(tail) = 0.120591, SD(head) = 0.108584. Lag 2 Mean(tail) = 0.898, Mean(head) = 1.026, SD(tail) = 0.122963, SD(head) = 0.085615. Thank you!

[@kevinnicosurposa4128]

Yeah me too :( did you find out why?

[@JoshCaiLovzu]

@@kevinnicosurposa4128 not yet, and don't know why... lol

[@71Deba]

Great!. Thanks Ed.

[@MOHANED256]

Thank you,very interesting and helpful.

[@YalXABfactor2863]

Very interesting

[@ericdoe1129]

Thank you.

[@Math342010]

Thanks for the vid. So far, this is the great one. But, is there any way to calculate/estimate multidirectional variogram? I don't know how to interpret it.

[@lahcenrerbal5893]

Thank you a lot Mr.

[@oliverangelil7742]

Unbelievable video

[@authenticwarrior7877]

nicely explained!!!

[@Hippie7733]

Man, what the heck is a variogram indeed. Thanks

[@henryadolfo]

Very interesting video !!!!

[@Chucho930311]

Taking into account that the profile 1 apparently shows less variance, why its values look further apart that the ones in the profile 2 which have more variance ?

[@N0RRec]

Dear Mr. Isaaks, can you recommend any literature on the topic of kriging/cokrigin and variograms?

[@sadeddy]

Try "An Introduction to Applied Geostatistics" by Isaaks and Srivastava, Oxford University Press

[@sarelapalacios7054]

find very interesting WHERE CAN I FIND INFORMATION ON variogram pLEASE!!!

[@eghweridojoseph]

How do you calculate the parameters of your ordinary kriging, like the mean, variance, MSE, MAE, quarter, minimum etc, practical example

[@sadeddy]

I use JMP

[@eghweridojoseph]

Prof I will like to discuss with you on [e-mail] on some points

[@titikpinafally4939]

Thank you so much

[@blaze4404]

.... so were the subsequent videos never uploaded?

[@penny337]

Thank you so much!

[@declanahern3021]

Great tutorial. Where is part 2?

[@bjordan672]

Thank You!

[@kimmusak1611]

Thanks .. really nice

[@robertorolo]

Great class!

[@sadeddy]

Roberto Rolo I have some news -- I have posted two follow up videos on variography and will post the third today. hope you enjoy the videos. ed

[@robertorolo]

Of course! Your teaching skills are amazing. I'll check it out

[@ernestdunwoody2992]

Edward Isaaks Really great. You have done us all a service.

[@geilileo]

+Edward Isaaks great video, thanks. Can you tell me where to find the follow ups, I can't find them on your channel?

[@TheAd1ban]

Amazing

[@roylxp]

where is the part 2 and 3?!

[@RamiAlloush]

Great Video ,, could you please post the ppt file ?

[@zoozolplexOne]

cool !!!

[@J4NFK]

I feel absolutly dump but I was playing around with the given example and find out that Lag Statistics is absolutly wrong. For example, for Lag 2 the Tail mean = 0.91, Tail Std = 0.12, r=0.19, am I missing something? Thank you!

[@thedjjn777]

Did you ever get a reply?

[@sarelapalacios7054]

I'm interested in video but recently I am learning English understand a word, but my very interested in this topic, someone could help me please!!

[@LuisMan8]

if you want, I could help you... I speak spanish

[@ShaibalAhmed]

Mr. Edward, how are you doing these days?

[@awesome-ai1714]

So is Semi-Variogram a Variogram? I dont see any definitonsof Variogram, so what the heck is variogram?

[@Ramstagiova]

he probably passd away

[@maxhofmann9851]

Thank you very much for this video! However, I think your calculations are not correct, you seem to have included more than 40 datapoints per transect. In your first head-tail-scatterplot, there are 48 instead of 40 points for example. I also get different mean, sd values etc when I rerun the calculations with the 40 values that are shown in the lineplots.

[@AndruideAtario]

bad presentation. you have shown at no point practical implication, but just outlined formulas. I conclude that variograms are useless in practice and are just for somebody who likes to calculate numbers
