Within estimate: adjacent MR/d2, weighted R/d2 or S/c4, or pooled s/c4.
DF is a moment-matched approximation, not a claim of an exact chi-square law.
For overlapping MR, its variance includes the shared-observation covariance
under independent Gaussian observations (correlation of successive differences -1/2).
