data |
a numeric vector or class |
p |
a positive integer specifying the autoregressive order of the model. |
M |
|
params |
a real valued parameter vector specifying the model.
Symbol |
model |
is "GMAR", "StMAR", or "G-StMAR" model considered? In the G-StMAR model, the first |
restricted |
a logical argument stating whether the AR coefficients |
constraints |
specifies linear constraints imposed to each regime's autoregressive parameters separately.
The symbol |
parametrization |
is the model parametrized with the "intercepts" |
Numerical integration is employed if the quantile residuals cannot be obtained analytically with the hypergeometric function using the package 'gsl'.
Returns a (Tx1)
numeric vector containing the quantile residuals of the specified GMAR, StMAR or G-StMAR model.
Note that there are no quantile residuals for the first p
observations as they are the initial values.
