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. 🙌🙌🙌
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.
Excellent video. Very clear speaking voice and thoroughly explained. Highly professional. Thank you, it helped a lot. Eagerly looking forward to the next series.
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!
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?
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
Many thanks for this great video. But i can't find the next 2 videos (Calculating directional sample variograms & Modeling directional sample variograms).
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.
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!
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!
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 ?
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.
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
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. 🙌🙌🙌
The best geostatistics explanation on youtube. Thank you !
Excellent! Finally I have come to a site where I begin to understand this matter of the variograms
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.
Thank you for such exemplary and clear explanations of the variogram and other concepts 🙌!
Wow, this is a memorable class. I am falling in love with spatial statistics. Keep up the good work
Fantastic video! Very clear, comparing with my sleepy "docents" at the uni, til today I finally understood!Thank you!
Great video, unfortunately I couldn't find the next video on variogram.
You’ve perfectly described my entire semester in geostatistics thank you!!
This explanation is so good that at some point I just knew you hold a PhD, which you do. Thanks a lot!
Excellent video. Very clear speaking voice and thoroughly explained. Highly professional. Thank you, it helped a lot. Eagerly looking forward to the next series.
Very interesting and well organized presentation and teacher. Really I benefited from this video. Many thanks!
Edward Isaaks, you're a genius. Great explanation, thank you very much.
Thank you so much!!!! It's absolutely terrific teaching about Variogram!! Cleared all my questions!! Very easy to understand. Best Ever!
Very nicely explained,Simply loved the style of presentation in a crisp and clear voice.Waiting eagerly for next videos upload.
You are a great teacher. Love ur teaching
excellent class you are a great teacher. I had trouble understanding these concepts and books didn't help. saludos desde Perú
Thanks Edward, I finally understood this important concept, because of you!
Great video, excellent introduction. Really appreciate you putting this together.
Highly professional and fascinating explanation! Thank you, sir.
Excellent explanation ... I had been struggling for more than one year to understand the difference between correlogram and semi-variogram ...

Anyhow I was unable to fully understand the concepts, until I stumbled upon this video. Many Thanks Dr. Isaaks!
Great explanation! I liked the use of geometry for the semivariogram concept, thanks!
Thanks this plus the chapter in your book were a big help to this geoscientist!
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
Awesome Explanation. Thank you. Please share the rest of the videos.
Please have you seen the rest of the videos? If yes, could you share them with me? rvihotogbel@yahoo.fr
Great video, easy to interpret, looking forward to next two lectures. Thank you .
How powerful can the internet be? Dear Mr. Edward Isaaks, thank you for your efforts.
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?
I have the same issue with the video!
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
Fantastic teaching, excellent lesson!
thanks a lot. i was having a problem understanding the matter and this helps! xoxo
Thank you so much for the video/explanation! You're a great teacher.
Fantatisc! Very clear!
Great content! Loved it!
Wow, excellent video presentation. Thank you.
demystifying indeed. i really appreciate this class.
Thank you for uploading this great video, looking forward for more,
So nicely explained
My Masters looks at sediment and rivers so your video was very pertinent. Your explanation is fantastic. Thank you very much.
You probably don’t realize but this is the great Isaaks who wrote with Srivastava An Introduction to Applied Geostatistics. Thank you very much
Thank-you for a very clear explanation.
Really appreciate the explanation, how can I find the other two videos?
Eduard, that's a fantastic work!
Beautiful style of explaining a segment of statistics, which is surprisingly made 'A mother of complexity' and people want to stay away from it. :)
Very good explanation! Thanks for your vid.
Is spatial continuity essentially the same things as positive spatial autocorrelation?
Great explanation, thanks!
such a great explanation! thanks so much!!
Many thanks for this great video. But i can't find the next 2 videos (Calculating directional sample variograms & Modeling directional sample variograms).
I also can not find the next 2 videos.
Good video. Could you please upload the other videos?
Many thanks for the vid. It was very helpful! Could you upload the other parts too?
Awesome video

Yeah me too :( did you find out why?
@@kevinnicosurposa4128 not yet, and don't know why... lol
I wish I had seen this beautiful resume earlier...
.... so were the subsequent videos never uploaded?
Very easy and informative .. where is the 2nd video?
I like a lot this explanation. Thank you.
Dear Mr. Isaaks, can you recommend any literature on the topic of kriging/cokrigin and variograms?
Try "An Introduction to Applied Geostatistics" by Isaaks and Srivastava, Oxford University Press
Excellent!
Excelent explanation, thank you!
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 ?
Amazing video. Thanks a lot
find very interesting WHERE CAN I FIND INFORMATION ON variogram
pLEASE!!!
Excellent
Thanks, that was terrific!
Thank you,very interesting and helpful.
Great tutorial. Where is part 2?
How do you calculate the parameters of your ordinary kriging, like the mean, variance, MSE, MAE, quarter, minimum etc, practical example
I use JMP
Prof I will like to discuss with you on eghwerido.joseph@fupre.edu.ng on some points
Very interesting video !!!!
Man, what the heck is a variogram indeed.
Thanks
Great!. Thanks Ed.
Thank you a lot Mr.
Very interesting
Unbelievable video
nicely explained!!!
Thanks very much.
where is the part 2 and 3?!
Great Video ,, could you please post the ppt file ?
Did you ever get a reply?
Great class!
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
Of course! Your teaching skills are amazing. I'll check it out
Edward Isaaks Really great. You have done us all a service.
+Edward Isaaks great video, thanks. Can you tell me where to find the follow ups, I can't find them on your channel?
Thank you.
Thank you so much!
Thanks .. really nice
Thank You!
So is Semi-Variogram a Variogram? I dont see any definitonsof Variogram, so what the heck is variogram?
Thank you so much
Amazing
cool !!!
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!!
if you want, I could help you... I speak spanish
Mr. Edward, how are you doing these days?
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.

he probably passd away
