Rolling statistics and stationarity in Time series | How to Check stationarity of a time series

[@MateiCatana21]

Thank you very much your videos saved me from failing the exam! I really appreciate the way you teach, you make it easy to understand. Thank you!

[@AshrafulAlam-]

Outstanding lecture! Love it. Thanks very much

[@MrRynRules]

Thank you Sir, well Explained.

[@dipendrapratap6495]

Superb explanation sir🎉🎉

[@RamanKumar-ss2ro]

Good one again.

[@UnfoldDataScience]

Thanks a lot :)

[@komalilyaslamok]

great work

[@UnfoldDataScience]

Thanks Komal.

[@ashishbhatnagar9590]

Nice video Sir. Very helpful.

[@UnfoldDataScience]

Thanks Ashish :)

[@robertbencze8205]

For stationarity, did you assume that the time series comes from a kind of special random variable (wide sense stationarity I assume is the term) that has the random mean equal to its mean in time?

very good explanation .. thanks

You really deserve a lot more !!! Loved it

[@UnfoldDataScience]

Thank you so much Mohammad.

Absolutely..within just 8 mins I understood the crux

[@krishnab6444]

nicely and properly explained sir

You are great sir I saw your many videos. encluding Time series and machine learning

[@UnfoldDataScience]

Thanks Rutvik.

got it. Thank you.

[@UnfoldDataScience]

You're welcome!

What value is now T6

[@rutvikjaiswal4986]

make a video on What is the ADFuller test? How to understand it properly? How to analyze it! please make a video on it! thank you in advance!

Great job Aman..!

[@UnfoldDataScience]

Thanks a lot Shrikant.

[@CHRISTYGEORGE-u7s]

even if time series is not stationary we can still apply ml methods like lstms right ?

[@navketan1965]

Sir, If I am doing double exponential smoothing 5 period moving average with a software program-after 5 period exponential moving average is calculated say (X) does computer do second calculation with data X and (X-t1) (X-t2) (X-t3) (X-t4) - - - forgive me,I went to college 50 years ago..(X-t1) is exponential moving average one period prior & so on.Thank you.

Bro, please buy big board. Your teaching is very good.

[@UnfoldDataScience]

Thanks Gotham. Sure will try.

[@akshatapalsule2940]

Sir you are best !!

[@UnfoldDataScience]

Thank you Akshata.

[@sadhnarai8757]

Very good Aman

[@UnfoldDataScience]

Thank you :)

[@amadoum.jallow620]

How do you determine the window? Is it that you can input any figure?

[@UnfoldDataScience]

Depends on what server our purpose, like for what we want to it. Will discuss details in upcoming video.

[@AyubAli-up4bc]

@@UnfoldDataScience okay thnx sir....

[@lovleenkaur1042]

Why do we need the TS to be stationary for ML training?

[@madhur4255]

Thank you, Excellent presentation

[@UnfoldDataScience]

Welcome Madhu.

[@testingyoutube915]

Can you provide notes as well

[@cdhanunjay5497]

1) I have a data of daily sales for 10months when i apply the seasonal difference how can i take the shift ? 2) after doing the seasonal difference or any other method to make stationary is it necessary to bring back to the normal units

[@siddharthaborpuzari9000]

Thanks a lot..excellent playlist

[@CrisaliDan]

I cannot find your course. Could u give me a Website or link ? Thank you

[@UnfoldDataScience]

[@purvanyatyagi2494]

sir , i want to train an audio denoising algorithm should I go with CNN or there is a better algo.

[@purvanyatyagi2494]

i have also seen a algo using Gaussian mixture to predict noise in audio

[@UnfoldDataScience]

Gaussian mixtures should perform good.

[@kunal1906]

530+420 = 950/2 = 475 thank you for this method

[@pusarlaaishwarya5035]

What is compositional data?

[@AyubAli-up4bc]

SLM sir, how to plot the accuracy of different model

[@UnfoldDataScience]

Hi Ayub. We can put accuracy numbers and model name in different list/array and plot.

[@i_amanrajput]

Excellent brother ! You nailed it . I have become your huge fan

[@UnfoldDataScience]

Thanks a lot Aman 😇, please share with others as well who could be benefitted from such content

[@dr.unmeshedwankar2005]

Thank you for all the amazing videos!

[@UnfoldDataScience]

Glad you like them!

[@ayantikabhowmik1261]

Sir why do we need to make the time series stationary before applying any machine learning algorithm?

[@VinodRS01]

+1

[@UnfoldDataScience]

Answered :)

[@philemonkrop7399]

So what's the answer

[@smartzen110]

Still this smoothing method needs to be validated with other techniques
