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: "pandas offers us the .corr() method to use with DataFrames as follows."

A block of code is set as follows:

lin_model = sm.OLS(metal_data['alloy_hardness'], X)

my_model = lin_model.fit()

print(my_model.summary())

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

import pandas as pd

my_data = pd.read_csv('Datasets/auto-mpg.data.csv')

my_data.head()x1 and x2:  -0.9335045017430936

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "Select System info from the Administration panel."
