⚠️There's a newer version (0.3.15) of this package.Take me there.

season

R package to run seasonal analyses in time series. For details see our book "Analysing Seasonal Health Data" (2010) https://www.springer.com/gp/book/9783642107474.

Useful functions are:

  • casecross for case-crossover analysis
  • nscosinor to estimate non-stationary seasonal patterns using the Kalman filter
  • nonlintest for a time domain test of non-linearity
