Order of earthquakes
In this exercise you will use the ACF and PACF plots to decide on the most appropriate order to forecast the earthquakes time series.
AR(p) | MA(q) | ARMA(p,q) | |
---|---|---|---|
ACF | Tails off | Cuts off after lag q | Tails off |
PACF | Cuts off after lag p | Tails off | Tails off |
The earthquakes time series earthquake
, the plot_acf()
, and plot_pacf()
functions, and the ARIMA
model class are available in your environment.

Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Create figure
fig, (ax1, ax2) = plt.subplots(2,1, figsize=(12,8))
# Plot ACF and PACF
____(____, ____=____, ____=____, ax=ax1)
____(____, ____=____, ____=____, ax=ax2)
# Show plot
plt.show()
