Frequentist model comparison tests of sinusoidal variations in
  measurements of Newton's gravitational constant
  Anderson et al have claimed to find evidence for periodic sinusoidal
variations (period=5.9 years) in measurements of Newton's Gravitational
constant. These claims have been disputed by Pitkin. Using Bayesian model
comparison, he argues that a model with an unknown Gaussian noise component is
favored over any periodic variations by more than $e^{30}$. We re-examine the
claims of Anderson et al using frequentist model comparison tests, both with
and without errors in the measurement times. Our findings lend support to
Pitkin's claim that a constant term along with an unknown systematic offset
provides a better fit to the measurements of Newton's constant, compared to any
sinusoidal variations.
