Creates initial values for the non-stationary cosinor decomposition
nscosinor. For internal use only.
a data frame.
response variable.
vector of smoothing parameters, tau[1] for trend, tau[2] for 1st seasonal parameter, tau[3] for 2nd seasonal parameter, etc. Larger values of tau allow more change between observations and hence a greater potential flexibility in the trend and season.
distance between observations (lambda=1/12 for monthly data, default).
number of seasons.
