Your video is extremely useful, I was suffering from having no idea of putting p,d,q parameters into the model. Thanks to your explanation that it makes clear about what these parameters are by applying differencing values and plotting out PACF to determine the parameters, compared to other lecture materials.
@@DecisionForest Wow ! Thanks a lot. That saves me plenty of time to figure it out. Indeed. Also, I am currently facing another problem, which is as I followed your instruction and detremine p, d, q parameters, however, p and q are great numbers, such as 18 and 30, respectively. How long does it take the computer to generate the ARIMA model? Also, is it normal that the parameters would be so huge ?
@@DecisionForest Ok. In my partial auto-correlation correlogram, there are no numbers exceeding the significance line, for p value, only 1, 8 and 18, 30 are closest to the line but below the line. Should I pick 1 for p instead? Similarly, for q value, in autocorrelation diagram, 1, 18 and 30 are closest to the significance line and below the line. Should I pick 1 instead ?
I was taught that we can only use ACP y PACP when working with either AR or MA models separately, because when combining them this aproach to select p and q is not longer valid. The right aproach would be creating the ARIMA(1,1,1) model and analyzing the residual ACP instead of the two previously mentionated, am I right? or could you please explain me why are you using them this way?
Very well explained and helpful but I do not understand one thing: what is the criteria of choosing p and q? Is it the value above the significance level laying the closest to zero or what?
What about using Auto Arima which gets us the best order for p,d,q values for our ARIMA model? Will there be different answers if I choose your method to get each of p,d,q values separately?
I kind of confused about this whole thing. The prediction line is always behind the price... It should tell us what's gonna happen before it happens... Not after its happens
Hi, one question, how i check next prediction, it possible predict next day, or next few days, this is what i not understand in this model. All models which i did before, like linear regression, it was easy, i take features or feature split data for train and test, and after i add some data to predict it, here i not understand how to do it.
That's the mistake being done over and over. Wherever I go looking up some forecasting techniques, most youtubers and bloggers fall underneath this problem of lagged predictions. I came across a workaround which is not easy though. It is trying to predict the differenced value of the target variable (i.e: pct_change) this way the task of predicting is becoming more difficult but at least prediction scores (good or bad) will be real and not misleading.
How can I know what the closing price this model is projecting for the next day? Supposing that I used data between the period 01/01/20 and 07/01/20? I want to know what the predicted value for 08/01/20. Thanks.
Agree, don't get this. If you keep the prices at the same level and just increase the time, the prediction would swing around the same value. Looks like just fitting a graph to another :P
Thank you @decisionForest. You have explained very clearly. I had doubt to find the value of p,q.After this video, I am clear about p,q.It would be great if you give the access for code. I have sign up DecisionFores but unable to get the code. Thank you.
Thank you, glad you found the explanations helpful. Just checked the url, if you click on the link and you are logged in, the download starts automatically.
Thanks for your reply. I have some questions regarding p,q. My understanding for calculating p is in this way: We need to count the number of spikes which are above critical line?Is this understanding correct regarding p using PACF?And I am following the same approach for calculating q value using ACF?i Is my understanding correct?
Hi, the ARIMA module has been shifted to: from statsmodels.tsa.arima.model import ARIMA And when I use its summary I get SARIMAX summary. What's wrong?

This video really helped me to finsh my College project. The way you explained is just awesome. Thanks a lot
Glad I could help mate, comments like yours make recording these tutorials worth it.

Very happy it helped, these parameters were a black box to me as well for a long time

@@vsvm8769 these are huge numbers for differencing and such, it should be in the low single digits usually, try analysing again

@@vsvm8769 yes, 1 it is then for both
Can you explain how you chose q=3 from the graph. I could not get it.
Amazing video, a hidden gem man, just subbed, thank you!
Thanks mate! Glad it was useful.
Thank you for your instruction. Could you explain how did you choose q value base on autocorrelation?
I was taught that we can only use ACP y PACP when working with either AR or MA models separately, because when combining them this aproach to select p and q is not longer valid. The right aproach would be creating the ARIMA(1,1,1) model and analyzing the residual ACP instead of the two previously mentionated, am I right? or could you please explain me why are you using them this way?
I understand nothing. There must be better, clear way to explain what is p and what is q.

This is also my question
The website and the Jupiter codes you have given is not working. Showing URL error
@13:15 use "from statsmodels.tsa.arima.model import ARIMA" instead of from "statsmodels.tsa.arima_model import ARIMA" and "result = model.fit()"
you have no idea how much you have helped me, thanks a fuckin ton
Why would you make the data Stationary if you are using the original data to fit ARIMA?
Is there way to store the value of p and q in a variable without having to analyze the chart like how we did for d?
Thanks. I did not understand how you chose q though, is it the lowest value in the graph stading out?

Thank you for explanation.
You're awesome teacher ! take love brother.
Thank you sir!
I am not able to access the notebook. need help in it

Hi, arima model can get a value of r-squared? how?
Hello, why is the forecast lagging behind the price?
That's the mistake being done over and over. Wherever I go looking up some forecasting techniques, most youtubers and bloggers fall underneath this problem of lagged predictions. I came across a workaround which is not easy though. It is trying to predict the differenced value of the target variable (i.e: pct_change) this way the task of predicting is becoming more difficult but at least prediction scores (good or bad) will be real and not misleading.
can we get p and q as 0?
since I'm not getting any data points in auto and partial correlation
Very good explanation. Thank you
Glad it was helpful!

I get no change in my autocorrelation plot even when i apply differencing. Why might this be? Thanks!
I had forgotten to update the df.price in the plot_acf function. once i replaced it with the newly created diff variable it worked ! :D
EXcellent.
If we pass df.diff() in the plot acf or pcf function , can we consider d as 0 then as we are passing the differenced series?
you can do it, but when you build model, d have to use this diff_data for your model, if you use original data, d have to be 1.
Sir, can time series forecasting be applied to the percentage change of the closing prices of stocks?
like can it be used to predict future retruns based on past returns?
Yes for sure
@@DecisionForest okay! thank you!
arima just say tomorow will be like today)
can i download your code or file
hey i was wondering where did u get the hourly time
It’s historical data from Interactive Brokers.
Could you share me the python file ?

Hi Pradeep, you can find a download link in the description, notebook is hosted on my website.
can i get your code?
fucking scam didn't get any notebook there
all this math stuff is useless waste of time, doesnt work.
