![USEFUL OR TRASH? Kurtosis and Skewness [WATCH THIS, BEFORE YOU USE]](http://i.ytimg.com/vi/Nhpe0uSf0Ts/mqdefault.jpg)
Fantastic Video! It clarified my entire concept in one go! Subbed and shared with my friends
Awesome, thank you!
This was really well explained! Relating it to the same concept in physics was very helpful
Thanks Karl! The concept of Moments belongs to Physics and gets picked up in Statistics.
You deserve 500k+ subscribers at this point of time
Thanks for the compliment. Do help the channel by sharing the video with your friends and acquaintances.
Professor, I have no doubt saying that your video is the best video on moments in statistics. I've watched a lot of videos on this subject and yours is the only one that made me finally understand this concept. Thank you so much! You got another subscriber! 😄
Pedro, you are very welcome! I am happy you found the content useful.
This is the best explanation I've seen, thank you so much!
Thank you. Glad you found it useful. Do share with your friends and acquaintances. It helps the channel to reach out to more like-minded people.
Very good explanation, you need to put more videos
you cleared my doubts regarding moments in conceptual way. and i am not able to express what i am feeling exactly but you did a grat job
Thanks. Do subscribe to the channel and share the video with more people.
excellent explanation. thank you !
Thank you. Do share and subscribe. It help the channel.
THIS IS SO GOOOD, THANK YOU!!!
Thanks.
You made it so easy!!! Thank you so much.
You're so welcome! Glad it was useful! Do share and subscribe to the channel.
Thanks a lot for this nice concept of moments!
Thank you!
This is just a the best explanation ever!
Thanks. Do subscribe and share if you liked the content. 😀
Extremely well done
Thank you.
Thank you sir.....yur explanation is amazing
Glad you found it useful.
very helpful, thank you
Glad it was helpful! You are welcome!
Unexpected explanation 🙏
Thanks. Glad you liked it.
Sir please make a video on variance and standard deviations and how to analyse data on basis of them . Pls
Please check the playlists. These videos are already available.
Your videos are awesome
Thank you. Please do share with your friends and subscribe. It helps the channel immensely!
Very good explanation sir
Thanks for liking
What an explanation sir
Thanks and welcome
thank you
Welcome!
Very useful
Thanks a lot♡
Glad it was helpful!
Amazing 👍
Thanks 😄
Good morning sir Can u help in finding Geometric Brownian motion in Statics. Which is concept of Physics
Lookup Black-Scholes Model. I believe you are already aware of it as it is a part of the CFA syllabus!
Thanks, finaly. But I hope you do the same video with economic example instead of physics the next time... Thanks again
The "moments" as a concept is derived from Physics and not from Economics.
I please do video on degree of freedom...
After watching this all the doutes are clear, after investing 1 and half day on moment I finally landed on this video and within 15 min all are clear. Thanks a lot
Noted. Coming soon.
Video on degrees of freedom has been released
CORRECTION: Typographical error: The SD of 2.5 is actually Variance. The correct SD without considering it as a sample is square-root of 2.5 = 1.58. However, this DOES NOT CHANGE the essence of the context and the content.
Can you plz do more videos about this concept of moments
Like factorial, absolute moments and moments of bivariate random variables
Sure. However, the concept of 'moment' will NOT change. What needs to be understood is that a moment is around/about a certain defined point e.g. a mean. So, the video may effectively end up as a repetition of the concept. Thank you for suggesting the topic.
@@LearningPuree thx for ur response. I got ur point ,sir i want to understand the idea behind why we using the factorial or the absolute and when we do that it's like understanding the intuitive part behind these concepts. I hope u understand what I'm takin about, cuz my English isn't that good.
Yes. sure.
Is there a video on degrees of Freedom on your channel?
nevermind, I just saw
👍👍 😃
Yes. There is one.
I don't understand the part where you made "the second moment independent of the first moment". It is independent in what sense can you elaborate?
Please see the formula for the second moment. We deduct the Mean which is the first moment. So, in a way we are removing the effect of mean in the calculation of the second moment.
Sir thanks a lot for ur videos,I am a strategist need your time, hw to contact pls
You can connect with me on my email ID on the channel.
@@LearningPuree sir pls drop mail id
You could have become a very good Physics Teacher
Thanks. I have a good background in Applied Physics 😀.
@@LearningPuree That's really great...
If possible, please make videos on applied statistics from very beginning....
Videos in bits and pieces don't help much ..
@Gangaprasad Tewary This format is meant to clarify topic specific concepts. Statistics & its application is a subject by itself and needs to be studied as a part of a time and resource intensive comprehensive course that has a commercial component. To say the least, even the bits and pieces component takes a considerable investment of time and resources to produce the content.
@@LearningPuree I totally agree with you.... down the line you can think to commercialize it....
Your contents and way of presentation are really meaningful!!
All the best!!
Thanks. I truly appreciate the feedback and communication with the viewers like you. It provides a compelling reason to invest the time in making these vids. 😀
Second moment =2.5 for 3,4,6,7. how ??
Thanks for pointing it out. It is a typographical error. I had written the variance value by mistake. The necessary correction has been made in the comments. However, with the correction the essence of the content and context DOES NOT change!!
best
Thanks!
Second moment is 110 and 100 for the data sets.. given..i really don't understand..how . Moments is when you actually divide that by 4 .. but ut just the added squares..
It is the squared distance when considered from origin as '0' (zero). Since the denominator is the same, it does not matter for the comparison. This was done only to simply and exemplify the point on shift of origin. The figures are correct. In fact when you move ahead in the tutorial you will notice the 2nd moment was also calculated using shift of origin to get 2.5 and 0 (zero) respectively for both cases. Hope this clarifies!
