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.

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

@@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 3 жыл бұрын

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

@@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 ?

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?

@robertaraujo347 Жыл бұрын

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 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

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?

@tillmannbrodbeck2430 3 жыл бұрын

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.

Hello, why is the forecast lagging behind the price?

@younesidsouguou7287 Жыл бұрын

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.

@adiredzic6726 3 жыл бұрын

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

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.
