AR(m) model
linear(x, m, d=1, steps=d, series, include = c( "const", "trend","none", "both"),
type=c("level", "diff", "ADF"), warn_root=TRUE)
x |
time series |
m , d , steps |
embedding dimension, time delay, forecasting steps |
series |
time series name (optional) |
include |
Type of deterministic regressors to include |
type |
Whether the variable is taken is level, difference or a mix (diff y= y-1, diff lags) as in the ADF test |
warn_root |
Whether to check (and warn) for roots outside the unit circle? |
AR(m) model:
x_{t+s} = \phi_0 + \phi_1 x_t + \phi_2 x_{t-d} + \dots + \phi_m x_{t -
(m-1)d} + \epsilon_{t+s}
A nlar
object, linear
subclass.
