Additive nonlinear autoregressive model.

1 | ```
aar(x, m, d=1, steps=d, series)
``` |

`x` |
time series |

`m, d, steps` |
embedding dimension, time delay, forecasting steps |

`series` |
time series name (optional) |

Nonparametric additive autoregressive model of the form:

*
x[t+steps] = mu + sum_j s_j(x[t-(j-1)d])
*

where *s_j* are nonparametric univariate functions of lagged time
series values. They are represented by cubic regression splines.
*s_j* are estimated together with their level of
smoothing using routines in the mgcv package (see references).

An object of class `nlar`

, subclass `aar`

, i.e. a list
with mostly internal structures for the fitted `gam`

object.
