Hi,
Could someone please tell me the R codes for fitting VAR(p) (Vector
Auto Regressive) models and doing the Johansen?s cointegration tests.

Fitting a regression model with with ARMA error
Hi,
I want to fit a regression model with one independent variable. The error
part should be fitted an ARMA process.
For example,
y_t = a + b*x_t + e_t where e_t is modelled as an ARMA process.
Please let me know how do I do this in R. What code should I use?
TIA

summary(price.df2)?
It gives two values for ?value of test statistic is: -1.5992?? 2.32?
one value is the t-test (or t-ratio), what is the other one?
Please help.
TIA

Fitting a GARCH model in R
Hi,
I want to fit a mean and variance model jointly.
For example I might want to fit an AR(2)-GARCH(1,1) model i.e.
r_t = constant_term1 + b*r_t-1 + c*r_t-2 + a_t
where a_t = sigma_t*epsilon_t
where sigma^2_t = constant_term2 + p*sigma^2_t-1 + q*a^2_t-1
i.e. R estimates a constant_term1, b, c, constant_term2, p, q
TIA

Subject: Re: [R] Fitting a GARCH model in R
Hello
You can find functions related to GARCH by searching on Rseek.org or
by running in R:
install.packages('sos', dep=T)
require(sos)
findFn('garch')

McLeod.Li.test
Hi,
I wanted to know that in the “McLeod.Li.test” P-value graph, at what level
is the dotted line drawn?
Also can it be changed?
Thanks.
