pmdarima.datasets.load_airpassengers

pmdarima.datasets.load_airpassengers(as_series=False, dtype=<class 'numpy.float64'>)

Monthly airline passengers.

The classic Box & Jenkins airline data. Monthly totals of international airline passengers, 1949 to 1960.

Parameters:

as_series : bool, optional (default=False)

Whether to return a Pandas series. If False, will return a 1d numpy array.

dtype : type, optional (default=np.float64)

The type to return for the array. Default is np.float64, which is used throughout the package as the default type.

Returns:

rslt : array-like, shape=(n_samples,)

The time series vector.

Notes

This is monthly data, so m should be set to 12 when using in a seasonal context.
