Analyzing data does not always go the way we wish.

And we often forget that even a simple visualization is a model.

Take a histogram.

The number of bins can significantly impact our interpretation.

Some people might suggest that...

"The information itself is great. The way of teaching is remarkable."**

What to expect?

Most courses on statistics don't discuss causality (even at top unis).

I'm always puzzled by this!

And for some time I wanted to change it.

Cannot Answer Exactly?

Try Causal Bounds

Answering causal questions might be difficult. Causal bounds offer a useful alternative when exact answers are not possible.

Why does it matter?

How would you approach a causal modeling problem where precise spatial (longitude and latitude) and temporal data is available?

Would you aggregate it?

If so, you would not be alone.

For the last 50 years, we've designed cars to be safe...

For the 50th-percentile male.

Well, that's actually not 100% correct.

According to Stanford's report**, we introduced "female" crash test dummies in the 1960s, but...

AI: Is Moral Reasoning Possible Without Causal Reasoning?

Perhaps.

Consequentialist view on ethics require us to consider how our actions will affect others and/or the environment in which we act.

For the last 24 months, I've been waiting patiently for LLMs to take my data science job...

What's the Hassle with Positivity?

And Why This Confusing Name?

Positivity (also known as overlap -- perhaps a better name) is one of the most fundamental assumptions for a broad variety of causal inference methods.

Building DAGs for supply chain: always fun, sometimes a challenge

If you have experience with causal analysis for supply chains -- what's one lesson that you'd share with your intern on day 1?

For me it'd be: be explicit about time order

Spoiler: Probably not, but here’s one thing that can improve your causal inferences
