Setup

Download dependencies

python -m pip install -r requirements.txt

Editing Content

Make changes to the content in the chapters directory.

To test

./runLocal.sh

And navigate on a browser to http://localhost:8000/

To recompile after you make changes

python compile.py

Warning: Never directly modify files in the en directory

Adding new Chapters / Examples

The book outline is defined in the file bookOutline.hjson. If you want to create a new chapter or a new worked example put it in there. Then run compile and you will see a skeleton directory created in chapters.

Using a Virtual Environment

You can optionally use a virtual environment.

Create virtual environment

python3 -m venv .venv

Enter virtual environment

source .venv/bin/activate

You should run source .venv/bin/activate everytime you start working from a new terminal session

probabilityforcomputerscientists's Issues

Independence Chapter Needs More

Importantly it doesn't include the definition of P(EF) = P(E)P(F)

Proof for multiple observations

It would be great to show a proof for this claim:
This is equivalent mathematically to calculating the posterior for one observation and calling the posterior your new prior

in the Digital Eye Test example

Consider consistent terminology for `product rule`

The following are all cited by students to mean the same thing. Perhaps they could be consolidated into one term.

• Product Rule of Counting
• Step Rule of Counting
• General Principle of Counting
• Fundamental Principle of Counting
• Distinct buckets method of Counting

Change sex ratio at birth example

Its a bit too contentious...

Multinomial needs improvement

en/part3/multinomial/

explain the origin of the PMF similar to multiple coin flips example

need a good example for the general law of total probability

All graphs need x-axis and y-axis labels

Missing <p> tags

Many paragraphs are missing p tags. This becomes an issue on mobile!

bug on display formula?

When cancel the selecting formula, there's a blank over the formula.

Fix the cs109 logo example

Categorical distribution?

The categorical is a multinomial with a single "dice" roll
https://en.wikipedia.org/wiki/Categorical_distribution

It often comes up in student questions, implicitly. It might be work including as a random variable!

Section on Sampling

In Part 2: Random Variables, we should have a section on drawing a sample from a random variable! It is such a useful concept (which we refer to many times). We could include inverse box sampling as a neat algorithm

An example may be missing here

Write a StAT example

It would be so cool. Use material from this quarters inference 2 lecture

Dart logo example is wanting

This demo needs a new figure and a lot more teaching:
