Thank you for such helpful video 💜 but i still can not get the fact that if we can forecast dependent variable out of sample!? As to forecast the dependent variable we will need future values of independent variables which are unknown! It will be so helpful if you kindly explain this.
@SatyajitPattnaik Жыл бұрын
In fbProphet, if you are performing a multivariate forecasting, in simple terms let say you are predicting y based on x1, x2, …. xn, then you need to future values of all x variables, one way to achieve is forecasting them individually using univariate forecasting and using those forecasted values to predict y

Hi Satyajit, great video! Question on Prophet, I've noticed the default model has some random initialization, doesn't return always the same result. Is it possible to set seed or disable randomization? I was thinking of maybe tune prophet parameters to have it run a simple linear regression (I know you can shutdown yearly and weekly seasonality), but haven't find my way around it. Any ideas? Great video, and great github resources, thanks for sharing!

Hey Nice Tutorial , My data is in year , month (quaters) format and I want to perform multivariate Timeseris for next 8 quarter , how can I achieve that ? Should I need to convert data in daily format and then make freq = Q ?? Please help
@taeefnajib Жыл бұрын
If your data is something like 2010-11, 2010-12, 2011-01... and so on, it is in a monthly format. 8 quarter is 2 years, which is 24 months. So if I understood correctly, you should do this: future_data = model.make_future_dataframe(periods=24, freq = 'M') Or you can aggregate the target for each quarters by summing up every 4 months, and then use quarter format. In that case, your freq would be 'Q' If I made any mistake, please correct me.

I don't see how this is multivariate, isn't multivariate when you have multiple correlated series which you want to predict at the same time? Here we need to know the future values for our additional regressors if we want to make future predictions. Much more like exogenous variables than for example a vector AutoRegression.
@SatyajitPattnaik Жыл бұрын
Multi variate simply means multiple variables, you can choose to predict multiple variables or a single variable which is dependent on multiple variables, both the scenarios comes under multi variate.

how can we calculate the metrics like RMSE, MAE, etc. ?
@SatyajitPattnaik2 жыл бұрын
Facebook prophet always does a out of boundary forecasts, in real time industrial implementations, we train a model on backdated day, and then calculate the rmse or mse for the test sampleset.. For ex: if you have Jan to Dec 2020 data, train till sep 2020, and forecast on Oct, Nov, Dec data, and then calculate rmse for these 3 month predictions, do that with all the algos, the lowest rmse model turns out to be the best model. This is the logic. Practically we can use sklearn metrics to calculate rmse, mse or any other regression metrics.
