(Deprecated) ARMA(p,q) correlation structure
Description
This function is deprecated. Please see arma
for the new syntax.
This functions is a constructor for the cor_arma
class, representing
an autoregression-moving average correlation structure of order (p, q).
Usage
cor_arma(formula = ~1, p = 0, q = 0, r = 0, cov = FALSE)
Arguments
formula |
A one sided formula of the form |
p |
A non-negative integer specifying the autoregressive (AR) order of the ARMA structure. Default is 0. |
q |
A non-negative integer specifying the moving average (MA) order of the ARMA structure. Default is 0. |
r |
No longer supported. |
cov |
A flag indicating whether ARMA effects should be estimated by
means of residual covariance matrices. This is currently only possible for
stationary ARMA effects of order 1. If the model family does not have
natural residuals, latent residuals are added automatically. If
|
Value
An object of class cor_arma
, representing an
autoregression-moving-average correlation structure.
