Using some software packages it is possible to 'regress out confounding variables from the independent variable x' before plotting x and y.
This makes me wonder: When it is motivated to regress out confounders from x, or both x and y, rather than just from y?

A "decision problem" can be modelled as :

A resource independent way of quantifying the hardness of a problem is to analyse how the size of a circuit scales with the input size $n$. The above problem scales exponentially ($2^n$) with input size $n$.
