    Just now I completed Marco Peixeiro Time series forcasting in python it takes 2 days to complete but you nicely summarize into 20 mins

    I sincerely appreciate it. Yesterday, I endeavored to implement the ARIMA model for the first time, utilizing the assistance of AI. However, I sought to deepen my understanding of the fundamental aspects of implementing the ARIMA model. That is the reason I was looking for a tutorial video. Your video significantly enhanced my understanding of the ARIMA model and the manual implementation process.

    For my p-value after the 1st difference, it was super small- like e-13, that doesn't seem right? (The p-value for original was 0.42)

    I am trying to make a Bitcoin time series forecasting model. I have followed all your steps but the forecasting model is giving the predictions as a straight line. Please suggest me where I'm going wrong.

    Hi, I would like to ask what is the final conclusion, prediction for the next 30 time periods. Since I see in Time series prediction plot comparison between prediction and reality why is there actual traffic available at the same time as prediction? Thank you.

    • @justintodata
      @justintodata  Год назад

      Hi, when modeling, you usually split the existing datasets into training and test sets. You use training to train the model and then use test to see the performance. Then you might apply it to a brand new dataset (e.g., in this example in the future without actual traffic) to make prediction.

    Does anyone else jsut get a completely flat forecast?
    When running
    forecast_test = model_fit.forecast(len(df_test))
    df['forecast_manual'] = [None]*len(df_train) + list(forecast_test)
    df.plot()
    It tells me that the length of values does not match the lenght of index
    if I just df.plot() i can see the two, but it (the forecast) is just a straight line, which given the strong upward trend isn't liekly the result

    Hi,
    I have one doubt regarding dividing dataset into train and test set. If using ACF and PACF plot for ARIMA modelling, should we divide the dataset or not? I have been told there is no need to divide the dataset if using ACF and PACF plots.

      Since we've logged it, you can use the exponential function in NumPy to switch it back

    IF I have missing days in dataset when values were 0. for example, sales data for products should I fill that points with 0 values to make predictions more accurate or I have to them missing as they are?

    • @justintodata
      @justintodata  Год назад

      Hi Giorgi, if they are really 0, my best guess is to fill them with 0.

    • @ryanmooney6741
      @ryanmooney6741 Год назад

      Print the variable you are trying to plot. You will likely see a sting on characters and then a list in the last element instead of the list being added as individual elements. I had to convert my data to a df to get it in the correct format to plot.
