comment How far do I need to drive to find an empty parking spot?
I thank whoever upvoted this after two years. It allowed me to look at it again to see the algebra error and correct the answer. A downvote might have been more appropriate, but the upvote is certainly appreciated. The answer now agrees with a simulation, so I am fairly confident that things are correct.

Fixed a braindead algebra error. Things should be correct now.

revised How far do I need to drive to find an empty parking spot?
Fixed typos and misspeaks (open for closed, etc.) Should be less confusing

comment Expected Value of an inefficient estimator of the $\beta$ parameter of a simple linear regression
$E[\tilde\beta]=\beta$ means the estimator is unbiased, not the same thing as consistency.

comment Measure of the set of periodic points of a measure preserving map
In the specific case I was looking at the maps are invertible. If that restriction makes the problem tractable, by all means use it.

comment Measure of the set of periodic points of a measure preserving map
That is what I meant by a rubber sheet, you are just pulling the outer ring, and the annulus stretches.

comment Measure of the set of periodic points of a measure preserving map
The region is convex, therefore connected, and the map is definitely continuous (piecewise linear for now, but the general continuous case is of interest).

comment Measure of the set of periodic points of a measure preserving map
Yes, I was assuming that $D$ was connected (in fact the case that I am interested in has $D$ convex. I have edited the question (which now feels like cheating).
