Re: [Gretl-users] gretl crashes consistently on Ubuntu 1404 as the 'OK' button is clicked.

All with the same gdt file.
gretl with windows 7 professional - ok
gretl with ubuntu 1404 - not ok
gretl with fedora 17 - ok
I went with Fedora 17 as it appeared to be the latest version at
32 bit. I think the gretl version I used on Ubuntu was 1.9.14 - I
am currently on the Fedora disk. That means that I cannot be sure
that the problem rests with Ubuntu or the version of gretl that I
was using.
The thing is that Ubuntu (with its Unity interface) "monkeys" with
the standard GTK GUI to produce an approximation to Apple's user
interface, and their monkeying seems to be buggy. We've seen this
before, and as Ignacio Diaz Emparanza mentioned in
http://lists.wfu.edu/pipermail/gretl-users/2014-June/010179.html
the workaround is to protect gretl from Unity by setting the
environment variable UBUNTU_MENUPROXY to a null value via
UBUNTU_MENUPROXY= # note: followed by a blank space
That should work, but if you prefer to use Fedora that's fine too.
If gretl crashed on clicking OK when installed "normally" (not as
hacked for Unity), we'd surely have heard about that long since.
Finally, the reason I was keen to use gretl (rather than my
expensive Minitab licence) is simply the output of the model - OLS
option is better / more compact and more readable than Minitab (
in my opinon). So once again thanks for that.
The next part of my current project involves applying data to a
Weibull distribution. I have been using Minitab for this for the
last 15 years but I am happy to move if something better is
available - any ideas?
You can use gretl's "mle" command to fit a Weibull distribution. You
might also want to look at the section on Duration models in the
chapter titled "Discrete and censored dependent variables" in the
Gretl User's Guide, which discusses gretl's built-in support for
models using the Weibull distribution, among others.
