Cross-Domain Results
The same DFA runs on very different signals. These are α values measured on bundled data; only the bearing pair is a normal-vs-fault comparison.
| Domain | Signal | DFA α | R² |
|---|---|---|---|
| Bearings | CWRU 12 kHz vibration, normal | 0.689 | |
| Bearings | CWRU 12 kHz vibration, inner-race fault | 0.183 | |
| Genome | Human chr1 GC% in 1 kb windows (struktura genome) | 0.967 | 0.980 |
Shuffle control
To check that a measured structure is real and not an artifact, permute the signal and run DFA again. If shuffling moves α toward 0.5, the order of the values carried the structure. struktura prove <file> runs this test with a bootstrap interval on α.
