Several formulas

When ATE, ATT and CATE are defined in those pages, the “i” subindex is maintained inside Expectations. These subindexes shouldn’t appear since Expectation is a property of the variable but not of its observations. Hence, in page 14, instead of

ATE=E[tau_i],

it should be

ATE=E[tau]

This happens several times in pages 14, 15 and 16. In page 19 and beyond this is corrected

First paragraph

Text says:
"In this graph, even if you don't condition on the collider, but condition on a cause of it, the causes of the collider become dependent."

The correct would be "condition on an effect/a child of it".

Code in [35]

Function name is "conditional_density" however this is the PDF of a normal distribution. NOT a f(X|Y=y) which is the probability density of X given a fixed value Y=y uses conditional mean, variance and derived from the correlation between X and y. So it was confusing for me.
As later in [36] you used Scipy.stats.norm.pdf function
Which is still just a normal pdf.
