Scaled 8–13 Hz EEG frequency ranges set in ds004148 at a 90% target contained 36 of 39 ds007176 V1 repeats

We tested ranges for a later EEG frequency. The measure was the posterior spectrum maximum frequency from 8 through 13 Hz. We treated ds007176 CE as closed eyes. Rules were set in 60 ds004148 adults. A separate ds007176 V1 set supplied 39 test values. Each record had 15 planned four-second windows. At least eight windows had to be accepted. The 90% calibration target used a fixed radius or a radius scaled by baseline bootstrap frequency SD. Fixed ranges contained 33 of 39 later values. Scaled ranges contained 36. Mean width was 1.45 Hz and 2.27 Hz, respectively. Mean score gain, fixed minus scaled, was -0.17 Hz. Joint 95% person bootstrap limits were [-1.30, 1.72] Hz. Thus, the data did not establish a score gain from scaling. All ten planned checks had score gain limits that included zero. Cohort differences mean that the target gives no 90% transfer coverage guarantee. Choices were fixed in a local plan before the new frequency calculation. The package preserves 232 compact spectra, source versions, code, predictions, draws, and reproduction commands. A second run matched all eight numeric result files. Two pinned raw record checks matched rebuilt arrays exactly.
