Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “To control Prophet’s automatic changepoint detection, you can modify both of these values with the n_changepoints and changepoint_range arguments during model instantiation."

A block of code is set as follows:

model = Prophet(seasonality_mode='multiplicative',
                yearly_seasonality=4,
                n_changepoints=5)

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

model = Prophet()
model.fit(df)
future = model.make_future_dataframe(periods=60, freq='MS')
forecast = model.predict(future)
fig = model.plot(forecast)
plt.show()

Any command-line input or output is written as follows:

pip install pystan
pip install prophet

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: “In the following seasonality plot, I’ve used the Toggle Spike Lines and Compare Data buttons from this toolbar to add further information to the hover tooltip.”
