I am unable to exactly find that ipython notebook in google drive folder. Please help me in finding that

[@sandeepcyno]

From where can I get the code of this video .

[@sckeshari]

How is Holt method different from Exponential moving average ? Just want to understand the logic behind Holt method.

[@UnfoldDataScience]

I will try to create video on that topic Saurabh

[@shrutiagarwal1193]

Sir this file I'm not able to find on your drive, kindly help it was really useful session

[@bhanuprasad_1718]

sir, i had watched your last video on this topic but am not able to get why those first 4 values are not preset

[@HARSHRAJ-2023]

Don't see any notebook for this in the google drive shared link. Can you please check from your side once.

[@UnfoldDataScience]

Its been sometime and somehow can't find this notebook in my local also. I will try again

[@sunnyarora4916]

In the previous video, you talked about double and triple exponential smoothing too but here you haven't, also how to optimize the value of window and alpha?

[@akashkumar-bq7cl]

yes same question even i have

[@UnfoldDataScience]

Thanks Hardik

[@shuznut]

I am glad that I found your channel. Thank you so much 😊

[@UnfoldDataScience]

Most Welcome.

[@valueray]

any idea how to code in python: how "respected" is as example the sma50? how much does it act as support/resistance with a measured and reliable number?

[@RajeshKumar-bl2oy]

Pandas data cast to numpy dtype of object. Check input data with np.asarray(data) - getting this error while attempt to fit a regression model in Python and fail to convert categorical variables to dummy variables first before fitting the model. can you please help fix this error

[@akshayam9539]

Great explanation. The only this is I can't find the dataset can you please include it in description so that we can also work on the same example dataset.

[@brunamoro8435]

Thank you for the so clear explanation! The only complain I've got is that I can't find the notebook in the repository website. And I would like to understand when I must use each of those.

[@RajveerSingh-jp1vs]

Great Explaination 👍
Appreciated ! keep it up

[@programmingwithjackchew903]

Why after applying the rolling and exponential smoothing, the p-value increases even exceed 0.05 compared to original dataset?

[@dishashaktawat2219]

can u provide the link of the dataset so that we can apply it on....

[@sandipansarkar9211]

finished watching

[@coolgrv9]

sir why the first 4 values are NaN for rolling mean method ?

[@gurpindersinghmuttar]

Why do we use holt since it is giving the same result as above

[@engineeringmind3961]

Sir any specific reason of choosing window = 5??

[@shaikirfanrahim7334]

instead of SMOTE which technique we will ise

[@premstein16]

Aman, can't find codes for smoothing techniques

[@UnfoldDataScience]

Hi Prem, can u check once now. I upload ed

[@premstein16]

Hello Aman, Thanks for your reply. I was looking for Time series smoothing in Python. Not able to find that.

[@UnfoldDataScience]

It's uploaded, could u check once please.

[@brendenandrews6965]

No aman it's not available in your time series file can you can please reupload it.. thanks..

[@amalaj4988]

Yes sir, its not there. Could you re-upload it?

[@rohitbhosale3617]

Thank you! Please provide dataset in further tutorials...so that we can practice

[@UnfoldDataScience]

Hi Rohit, did u look here?

[@aniruddhapal1997]

if red line(exponential trend) is exactly on the blue line(linear trend), can we say that the data has linear trend , not exponential trend ???

[@UnfoldDataScience]

Yes Aniruddha.

[@deepakrc8956]

Aman thank you for the explanation.

[@ishpen282]

Hello sir, how to get the rolling day average for exponential moving average, Ex: EMA(5)

[@UnfoldDataScience]

Python package will give dorectly.

[@teenamadhu7883]

Aman , really very thankful for your great explanation .through your explanation you make the topic simple and understandable.
I have a doubt here -
since exponential curve following the black one(original) can we say it is following exponential trend?

[@UnfoldDataScience]

Thanks. Yes

[@AkshayKumar-bj7lp]

hey Aman how do we select the value of alpha can we allow the model to choose the alpha value?

[@georgechristy11]

good question also which method to select out of the three?

[@mahmudsaideen6805]

Besides the massive knowledge you have. You are a legendary teacher

[@UnfoldDataScience]

Thanks a lot. pls share with friends.

[@jackyhuang6034]

Is holt the triple exponential you were talking about?

[@UnfoldDataScience]

Yes.

[@komalmaheshwari9626]

How do you decide that the window size is 5?

[@UnfoldDataScience]

[@nehaafreen3731]

can you please upload the code..can't find in drive

[@UnfoldDataScience]

Hi neha, Somehow that file is missing. I tried in search in my local machine but its taking time. I will put once I get it.

Thank you too!

very nice video sir

Thanks and welcome Ashish.

[@arifhasan904]

Why we use smoothening??

[@UnfoldDataScience]

Hi Arif, just for demonstration purpose.

[@arifhasan904]

Thanks @aman

Nice

Thanks Vinod.

Its possible to have subtitle in your video,because kinda hard for me to understand what you talking

Will look into it
