... it says exactly what they are, q0 is an arbitrary density on R^d, and x is a realization from that density, p1 is the transformed density. This is intro graduate level probability.

Oh absolutely, so it's all the more important to be precise in what we're estimating and for what purpose, and to be honest about our ability to estimate it with appropriate uncertainty quantification (such as by using conformal p

Are the entities interacting in any way here? That's pretty critical for agent based models as they enable complicated/unexpected emergent behavior from simplified rules due to the interactions of the entities.

I think they mean either what is E[x| y] (standard regression point estimate) along with a confidence interval (this assumes that the mean is a meaningful quantity), or the interval s.t. F(x | y) -- the PDF of x -- is between .025 and .975

Agreed! I also think it's extremely important as practitioners to know what we're even trying to estimate. Expected value (i.e. least squares regression) is the usual first thing to go for, does that even matter? We're probab

You're probably thinking of a predictive interval

That's not what a confidence interval is. A confidence interval is a random variable that covers the true value 95% of the time (assuming the model is correctly specified).
