Value

• n
  sample size.
• amp
  estimated amplitude.
• amp.scale
  the scale of the estimated amplitude (empty for standard regression; probability scale for logistic regession; absolute scale for Poisson regression).
• phase
  estimated peak phase on a time scale.
• lphase
  estimated low phase on a time scale (half a year after/before phase).
• significant
  statistically significant sinusoid (TRUE/FALSE).
• alpha
  statistically significance level.

Details

Summarises the sinusoidal seasonal pattern and tests whether there is statistically significant seasonality (assuming a smooth sinusoidal pattern). The amplitude describes the average height of the sinusoid, and the phase describes the location of the peak. The scale of the amplitude depends on the link function. For logistic regression the amplitude is given on a probability scale. For Poisson regression the amplitude is given on an absolute scale.
