```Dear Sola,

I don't know if the dataset is available online, but you can find another
illustration of Stata's mgarch commands here:

http://www.stata.com/stata12/multivariate-garch/

where the dataset is available from the Stata website, via the command:

webuse stocks

Using that dataset instead, you would be doing something like:

clear all
webuse stocks
tsset t
mgarch dcc (toyota nissan honda =, noconstant) , arch(1) garch(1)
tsset date
predict H*, variance dynamic(td(31dec2010))
tsline H_nissan_toyota H_honda_toyota H_honda_nissan, legend(rows(3))
tline(td(31dec2010))

In the above I used tsset t before mgarch to ensure that lags were
After tsappend I then tsset date in order to use tsline and graph wrt to
calendar dates.

In fact, I couldn't get tline(td(31dec2010)) to work, except like this:

tsline [...] tline(`=td(31dec2010)')

or like this:

scalar fdate = td(31dec2010)
tsline [...] tline(`=fdate')

```
tline(td(31dec2010)) is the syntax suggested by Rafal Raciborski, so there must be a way to make it work. Note that in the Stata help page cited above, tline is used with the value of t in the dataset, tline(2015) or tline(2016), depending on whether you include the last sample date or not; but for that to work you need to tsset wrt to t, otherwise if you tsset with the calendar date, you need to use tline(18627) (18627 is the distance to some time in the 1960s), which you can find from:
```
di td(31dec2010)

I think it's natural to plot wrt to calendar date, rather than wrt to

Now I'm very new to this and I'm not sure at all that's the right way to
do it, so if someone is listening it would be nice to hear if there's an
error.

Patrick.

```Hi All,
Sorry i did not include subject in the previous request i posted.
I read through The Stata News- vol 27 no 3, just sent to me.
The topic on Multivariate GARCH (MGARCH) written by Rafal Raciborski is
quite interesting and topical. Can anyboby please direct me to the
address where I can get the data the author used so that I can replicate
his result.
Olorunfemi, Sola.
