DAY 7 PYTHON PRACTICAL - BIS CENTRAL-BANK SPEECHES AS DATA

Open notebooks/day07_bis_speeches_student.ipynb from this folder and run the
cells in order. The default uses the frozen 2023 sample in data/teaching, so no
internet connection is required.

To collect the official BIS files programmatically, set USE_LIVE_BIS = True in
the setup cell and install gingado once with:

    pip install gingado

The live example requests 2021, 2022, and 2023. The frozen 48-speech file is a
stratified classroom sample, not a representative corpus and not suitable for
population prevalence estimates.
