### Quantile regression with missing values

Dear Grelt Users,
Is Quantile regression in Grelt contingent on the absence of missing values? Otherwise could some guru here-in gist me on what the qualm might be?
Cheers

"gretl", that is

Missing values at the start and/or end of the sample are
automatically discarded, but NAs inside the sample are not
accepted. If in context it is OK to discard such values, use
the "smpl" command to do so:

list Vars = y x1 x2
smpl ok(Vars) --restrict

Ho ho -- hold it

Seriously, isn't this new syntax being introduced a little hastily? So
far everything that could be accessed got its \$-accessor. This \$[] thing
seems to be all new. I'm not saying it's bad, but it seems to exist in
parallel to the old-style accessor. After all, all existing accessors
could now be re-defined, for example \$coeff -> \$["coeff"]. Maybe that's
the way to go (old-style accessors could be kept as syntactic sugar for
backward-compatibility).

Though I mentioned it here, the \$["name"] thing isn't really
ready for roll-out. To see what's available in that mode you
really have to grep the gretl sources for

gretl_model_set_data
gretl_model_set_double
gretl_model_set_int

and so on. These "set" functions are ways of attaching named
data for internal use, but the bundle-key syntax makes it easy
for users to grab a copy -- if you know what to look for.

Hi to all,
Folks I'm a little rusty...
What's now being meant by the 'roots' of an ARIMA model, please?

The roots of the AR and MA polynomials in the lag operator. They are at
the end of the model output that gretl produces. And Henrique was asking
for a way to save them for subsequent use in a script.

### Help with Gretl console

Sergio Mensitieri
Greetings,
I'm fairly new to Gretl and I have been trying to use the Gretl console, looking to replicate the examples on Principles of Econometrics by Atkins. However I can only enter a single line at a time in the gretl console. Can you tell me how to insert multiple lines in  the console without having to use a script?

Thanks
Sergio

### Re: Help with Gretl console

```Hi,

Usually multiple lines are separated by a \.

But I am not sure if command line accepts this.

Why don't you use the built-in commands editor? You can call back the
list of commands and edit them. Why not using scripts?

The nature of the console is that you enter a line, and that line is
executed; then you enter the next line, and so on.

If you don't like that, use the script editor. You can find it under
/File/Script files/New script, or use the "new script" icon (second
from the left) on the toolbar at the foot of the main gretl window.

### Copy and Pasting Scripts on Grelt Console

Hi All,
Could someone gist me if there's a means of copying and pasting scripts on the Grelt console? Indeed the monotony of retyping the same script on and again makes me sick.
