The extent to which survey experiments conducted with nonrepresentative convenience samples are generalizable to target populations depends critically on the degree of treatment effect heterogeneity.

Prompted by this question to the list 04Oct22, I replicate the problem with data set LTExercise distributed with the package. Essence of problem: covered area for each transect is computed as constant ...

The authors state that all data necessary for confirming the conclusions presented in the manuscript are represented fully within the manuscript. Supplemental ...

Abstract: Errors in power spectral density estimates are analyzed for a problem in which the estimator processes nonuniformly spaced data samples as if they were uniformly spaced (e.g., via fast ...

Generally, we expect that surveys representing the same target population should produce estimates that are consistent with one another; that is, measures taken at roughly the same time should not ...
