Hi all -
I'm having trouble getting TeX to work properly with Gretl 1.9.1 under Mac OS X
10.6.4.
Suppose for instance that I want to see the results of an OLS regression as TeX output
(the problem surfaces no matter what procedure I run). After running the regression I
choose the LaTeX drop-down menu and select View -> Tabular. I get an error box that
says it "Failed to process TeX file". On closing that error a log becomes
visible, saying at the beginning --
-----------
This is pdfTeX, Version 3.1415926-1.40.10 (TeX Live 2009) (format=pdflatex 2010.7.8) 8

entering extended mode

**\batchmode \input window

See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...
l.1 \begin{center}
You're in trouble here. Try typing <return> to proceed.
(more follows)
-----------
The problem seems to be that Gretl isn't using the gretlpre.tex file that I have
sitting in my working directory. I tried the sample gretlpre code in the current Gretl
manual. I also tried deleting the file (the manual says that if there's no
gretlpre.tex file the preamble defaults to the standard preamble). The problem remains.
When instead I choose to save the TeX output (rather than viewing it) the regression
results are indeed saved as a TeX file. but again lacks the preamble that's in
gretlpre.tex.
Any help appreciated.
Many thanks.

The default preamble definitely includes \begin{document} (and
works). I think gretl must be picking up a broken gretlpre.tex
from somewhere on your system. In the current snapshots (see
http://gretl.sourceforge.net/osx.html ) I have put a print to
stderr to track this. E.g on my system I see:
gretltex: using preamble file
/home/cottrell/gretl/gretlpre.tex
when I view a model. If you launch gretl from a terminal window
you should see what's happening, I hope.
cd /Applications/Gretl.app/Contents/Resources/bin
./gretl

Thanks for your quick response, Allin. In an effort to run a controlled experiment, I
tried to parallel your example as closely as possible by first deleting my existing Gretl
installation (from the Intel Mac disk images) by dragging my Gretl applications folder
into the trash and then installing the current snapshot (which I presume is the same or
really similar to what you're using) directly into my Applications folder.
The problem remains (no surprise), but now I have the benefit of your print to stderr.
Here's the xterm log when I (i) loaded Gretl from an open xterm, and (ii) tried to
view the results of an arbitrary OLS regression from the model's LaTeX menu:
--------------------------------------
bash-3.2$ cd /Applications/Gretl.app/Contents/Resources/bin
bash-3.2$ ./Gretl
(gretl_x11:3982): Gtk-WARNING **: Unable to find default local directory monitor type

periodicity: 1, maxobs: 36
observations range: 1960-1995
gretltex: using preamble file
/Users/rjlevins/gretl/
--------------------------------------
Re the warning and error messages -- Gretl seems to be confused to some degree. Any
thoughts as to what they might mean? Do these seem to be related to the problem?
The last two lines do seem to say that Gretl knows where to find the right preamble file.
But there's a difference from your output -- the filename of the gretlpre.tex file
isn't listed at the end (see last line above, compare to your example below). The
contents of that gretlpre.tex file are exactly as listed in the manual for the default:
--------------------------------------
\documentclass[11pt]{article}
\usepackage[latin1]{inputenc} %% but see below
\usepackage{amsmath}
\usepackage{dcolumn,longtable}
\begin{document}
\thispagestyle{empty}
The error log generated by Gretl was just like before:
--------------------------------------
This is pdfTeX, Version 3.1415926-1.40.10 (TeX Live 2009) (format=pdflatex 2010.7.8) 8

entering extended mode
%&-line parsing enabled.
**\batchmode \input window
(./window.tex
! LaTeX Error: Missing \begin{document}.
[etc. etc.]
-------------------------------------
This is all very puzzling. Thanks in advance for your help with this.

Thanks! That points me straight to a bug, now fixed. We were not
handling correctly the case where LANG is not defined in the
environment (and as a consequence you ended up with a "ghost"
gretl TeX preamble file). Seems odd; I haven't heard of that
before. One would expect something like LANG=en_US.UTF-8.

Allin -
The fix you made works. Thank you very much.
But one problem remains. Now I can save and copy LaTeX versions of my output. But the
View command still doesn't work properly. The pdf file that comes up is garbled.
See the attached. The file "Saved" was typeset using MacTex (TexShop/MacTeX
2009). The "Viewed" file was what came out when I used the View command rather
than Save.
Also, sometimes the View process stalls altogether.
This obviously isn't a critical issue - I still can generate the output. But it would
be better if View allowed me to view the formatted output.
Many thanks again,
- Bob

New subject: Multinomial Logit - getting the probabilties as predictions?
Hi there,
when performing a multinomial logit estimation Gretl gives as fitted values
a certain category for each id, which is nice. However, is there a quick way
to get the estimated probabilities
for each category and each id?
By the way, the command forecast in the multinomial logit window leads to a
crash of Gretl.
And for further development one could think of a "base" option, n'est pas?

If I'm not mistaken, here's how you could get the probabilities
for the keane.inp example in the gretl package:
<script>
open keane.gdt
list reg = const educ exper expersq black
smpl (year=87 && ok(reg)) --restrict
logit status reg --multinomial
scalar k = nelem(reg)
matrix b2 = $coeff[1:k]
matrix b3 = $coeff[k+1:]
matrix X = {reg}
matrix Xb = exp(1~(X*b2)~(X*b3))
matrix Probs = Xb ./ sumr(Xb)
print Probs
</script>
By the way, the command forecast in the multinomial logit window
leads to a
crash of Gretl.
Oops, thanks the report. That is not properly hooked up, so I've
disabled it for the moment.
And for further development one could think of a "base"
option,
n'est pas?
Yes, probably.

I hesitate to ask, but should that be 1 or exp(1) (=e) in the
first column of the matrix P as first defined?

Sorry, not as nice as it could be: there was a bug which biased
the fitted value towards prediction of the base case. This is now
fixed in CVS and the gretl snapshots for Windows and OS X. Thanks
for directing our attention to this area.
To make amends for this error ;-) I have now added an accessor
$mnlprobs. After estimation of a multinomial logit model this gets
a matrix of the outcome probabilities (rows = observations,
columns = outcomes).
logit ... --multinomial
matrix P = $mnlprobs
If you prefer, the columns can be extracted as series, as in
series P2 = $mnlprobs[,2]
No doubt this will get added to a GUI menu at some point, but
right now it's a command-line thing only.

I ran today's snapshot. This is very wierd.
I ran the new snapshot under an xterm. The "not moving" message you noted below
appeared. The window.tex file that was generated by the View command (on my system)
showed the same garbled result as before when the pdf came up automatically.
BUT when I instead typeset the same window.tex file manually (using TeXShop) the table
displayed perfectly.
So I'm at a bit of a loss. Some observations:
1. When I hit View in Gretl, the system fires up TeXShop and then the garbled pdf comes
up. Should TeXShop be starting? (TeXShop set itself to be the default viewer for TeX
source, but I don't know why it's starting up in this context. I would have
thought that pdflatex would be talking straight to the pdf viewer (in this case,
Acrobat).
2. I double-checked to make sure that the path to pdflatex I had in
Tools->Preferences->General->Programs actually pointed to a real file called
pdflatex. Indeed it does ('tho it's an alias).
Thanks for being so patient. The issue is starting to look more like a problem with the
typesetting system and less with Gretl. Sigh.

On OSes other than MS Windows and Mac OS X we offer the user a
choice of PDF viewer (under /Tools/Preferences). But on Windows
and OS X we assume the user has already selected a preferred
viewer, and we just issue a call to the OS to open the PDF file.
If TeXShop is coming up, that's OS X's decision. On a vanilla OS X
installation one might expect the Preview program to handle PDFs.
2. I double-checked to make sure that the path to pdflatex I

Or a problem with the default PDF viewer?
