Description

This class contains information on the periodic autoregressive parameters estimated by fit.piar.

Slots

p:

Object of class "numeric": The order of the PIAR model.

nls.parameters:

Object of class "matrix": Estimated coefficients of the non-linear PIAR model.

nls.res:

pdiff.data:

Object of class "ts": Periodically differenced data.

Methods

show:

Reports the periodic autoregressive coefficients estimates.

summary:

Like show, the periodically differenced data are also displayed.

plot:
