Generalized Lomb–Scargle analysis of $$\mathrm {^{90}Sr/^{90}Y}$$ 90 Sr / 90 Y

Abstract: 003, 2015). For this analysis, we made two different ansatze for the errors. For each peak in the LS periodogram, we evaluate the statistical significance using non-parametric bootstrap resampling. We find using both of these error models evidence for 11/year periodicity in the 90 Sr/ 90 Y data for two of the three samples, but at a lower significance than claimed by Sturrock et al. [1].

“…To independently verify some of these claims, we have analyzed some of the betadecay and solar neutrino data ourselves using robust statistical methods, for whatever data was accessible or made publicly available. Our analysis shows periodicities associated with solar rotation and annual modulation, although with a lower significance than claimed in some of the original works [23][24][25].…”

“…With this normalization, the L-S power varies between 0 and 1. This is similar to the normalization used in [24,25]. On the other hand, B18 (also [23]) used the normalization proposed by Scargle [29].…”

“…For this purpose, we independently re-analyzed both the BNL data, for which S16 found evidence for statistically significant peaks at multiple frequencies as well as the PTB data, for which P17 could not find any corroborative evidence at the same frequencies as in S16. We have used the generalized or floating-mean L-S periodogram [19] (similar to our previous works, where we analyzed the Super-K solar neutrino [8] and 90 Sr/ 90 Y decay data [9]), to look for periodicities in the frequency range from 0 to 14 per year, since this is the same frequency range, wherein which S16 found periodicities.…”
