Lyrics

[Verse 1]
Time series data flows like a river through the years
ARIMA breaks it down, makes the patterns crystal clear
AutoRegressive looks behind, Integrated makes it smooth
Moving Average finds the trend, that's how forecasters groove
Exponential smoothing weighs the recent more than past
Alpha beta gamma tune the forecast built to last

[Chorus]
A-R-I-M-A, Prophet shows the way
Exponential smoothing keeps the noise at bay
Lags and rolling windows, Fourier in the night
Tree-based strategies make the future bright
Time series forecasting, probability in sight

[Verse 2]
Prophet handles seasonality with additive and multiplicative flow
Holiday effects and changepoints help the model grow
Direct strategy trains each horizon on its own
Recursive takes one step ahead then builds upon what's shown
Multi-step or single-step, the choice will shape your game
Feature engineering holds the key to forecasting fame

[Chorus]
A-R-I-M-A, Prophet shows the way
Exponential smoothing keeps the noise at bay
Lags and rolling windows, Fourier in the night
Tree-based strategies make the future bright
Time series forecasting, probability in sight

[Bridge]
Temporal features are the gold we seek to find
Lagged variables tell us what we left behind
Rolling mean and standard deviation smooth the ride
Fourier transforms capture cycles deep inside
Random Forest, XGBoost trees can learn the temporal dance
Prediction intervals give uncertainty a chance

[Verse 3]
Probabilistic forecasting doesn't give just one result
Confidence bands and quantiles help us navigate tumult
Upper bounds and lower bounds embrace the unknown space
Mean absolute error tells us if we're keeping pace
Walk-forward validation keeps our models honest true
Backtesting on the past prepares us for what's new

[Chorus]
A-R-I-M-A, Prophet shows the way
Exponential smoothing keeps the noise at bay
Lags and rolling windows, Fourier in the night
Tree-based strategies make the future bright
Time series forecasting, probability in sight

[Outro]
From stationary data to the trends that rise and fall
Time series and forecasting, we can handle it all
Direct or recursive, the future's in our hands
With probability and intervals, we'll understand
