inlist()-problem
by artur tarassow
I've got another problem,
I am trying check whether the variable "time" is present in list L1. This
correct position is shown in the first example below. But if I add this
inlist-command to a function environment, the scalar check2 = 0 but should
be 2. I am using gretl (built: 2013-03-17) on Windows.
<hansl>
set messages off
set echo off
open denmark --quiet
#Works
ols LRM const time diff(LRM)
L1 = $xlist
scalar check1 = inlist(L1,const)
check1
scalar check2 = inlist(L1,time)
check2
#Within a function check2 gives the wrong result
ols LRM const time diff(LRM)
L1 = $xlist
function void Ltest (list L)
scalar check1 = inlist(L,const)
print check1
scalar check2 = inlist(L,time)
print check2
end function
Ltest(L1)
</hansl>

Error in function
by artur tarassow
Hi all,
I estimated a VAR model using the standard var-command and want to run a
function called varmodtest afterwards. The function simply exploits the
"modtest" command and merges different specification test results into a
matrix which is passed back.
<hansl>
function matrix varmodtest (scalar order "Lag length")
#Serial correlation
modtest order --autocorr --quiet
matrix OUTSC = $pvalue' | $test'
return OUTSC
end function
var 2 LRM IBO
matrix A = varmodtest(4)
<\hansl>
But I obtain the error:
"Can't do this: no model has been estimated yet
Data error
*** error in function varmodtest"
How can the function grab information from the previous VAR estimation?
Thanks in advance!

Re: [Gretl-users] gretl crashes after cvs update and build under Ubuntu 10.04
by yinung＠Gmail
Dear All
I just updated the cvs and built the gretl under my Ubuntu 10.04. However,
gretl crashes when I click in the mainmenu "Tools->Preferences->General."
I got an message as follows:
(gretl_x11:15034): Gtk-CRITICAL **: gtk_combo_box_append_text: assertion
`text != NULL' failed
I tried the same procedures to build the CVS and it seems OK under Ubuntu
11.04. Is it related to gtk* something?
Thanks,

Dataset handling in gretl (IDs, labels, standardization)
by Beek Pang
Dear gretl community,
I am using gretl and, recently, a number of issues came up when I was preparing a cross-sectional dataset for analysis. Specifically:
(1) Within gretl, is it possible to change the ordering of variables, and keep i.e. save this changed ordering? E.g. is it possible, in a dataset with 10 variables, to assign the variable which currently has the ID no. 7 another ID, e.g. the ID no. 2? I am asking because I often use gretl to "push" datasets into R, and it is convenient to have them ordered as desired when they appear in R already.
(2) Within gretl, suppose a dataset contains observation labels e.g. company names. Is it possible to remove all observation labels from the dataset so that there are none?
(3) Finally, I would like to standardize the regressors (not the dependent variable) in my dataset, such that each regressor has mean 0 and standard deviation of 1. Is there a "summary way" to do this e.g. by declaring the dataset to be a matrix, then operating on this matrix using some matrix operators?
Could anyone provide an idea how to resolve these issues,
please? I'd appreciate this a lot.
Thank you very much.
Kind regards
Beek

segfault while using restrict
by Ahmadou Dicko
Hi,
I have a problem with my installation of gretl on ArchLinux.
While trying to help on
SO<http://stackoverflow.com/questions/15997478/gretl-test-alpha-and-beta/159...>,
I get a segfault error
To reproduce this error
open murder_rates
ols executions const income lfp southern --quiet
restrict
b[income]=0
b[lfp]=1
end restrict
Using gretcli I get this error : Segmentation fault (core dumped)
I tried to desinstall it to make a clean install, but I didn't succeed.
Do you know how to proceed ?
I use the latest snapshot
gretlcli -v
gretl version 1.9.12cvs
uname -a
Linux dickoa 3.8.6-1-ARCH #1 SMP PREEMPT Sat Apr 6 07:27:01 CEST 2013
x86_64 GNU/Linux
I didn't make it also in make check
I get stucked at
*** Filip.dat ***
("Higher Level of Difficulty")
cholbeta: test[6] = 3.77499e-09
make[1]: *** [check] Segmentation fault (core dumped)
Thanks

Maybe a small bug in Chinese Language mode
by yinung＠Gmail
Dear Allin and all,
I found the following script works well in English Language mode but only
part of the output was shown in Chinese Language mode. The output seems to
be stopped after the fourth line (i.e., matrix Coeff = $coeff) in Chinese
Language mode. There are not further output beyong the fourth line of the
script.
It is however that the script was executed completely. This potential
Chinese-only bug occurs both in gretl 1.9.12 and 1.9.12 cvs under winXP.
But the script work normally under my ubuntu 10.04 in Chinese Language mode.
Thanks

open broiler

ols 1 xlist

matrix Stderr = $stderr
matrix Table1 = Coeff ~ Stderr

rownames(Table1, xlist)
print Table1

Strings: readfile, ANSI, and UTF-8
by Henrique Andrade
Dear Gretl developers,
I was analyzing some text files using the "readfile" function
and I realized that Gretl doesn't retrieve lines with accented
words when the .txt has the ANSI character encoding.
Please take a look at the following Hansl code (the text files
are attached to this e-mail):
<hansl>
string texto1 = readfile("C:\Users\henrique\Desktop\ANSI.txt")
print texto1
string texto2 = readfile("C:\Users\henrique\Desktop\UTF-8.txt")
print texto2
<hansl>
Is this an intended feature/behavior?
Best regards,
Henrique Andrade*

Creating matrix rownames from varname(X)
by Lee Adkins
I'm stumped on this one. I want to be able to automate the creation of a
results table that does not contain t-ratios or pvalues (or be able to
suppress the t-ratio and pvalues in modprint).
varname(xlist) produces a string with commas separating the names, but the
rownames command wants spaces instead of commas. So far I haven't been able
to get a proper string to use with rownames using loops.
<>
open broiler
list xlist = const 2 3 4 5
matrix X = { xlist }
vn = varname(xlist)
vn
<>
This produces the string that contains commas:
const,Y,PCHICK,PBEEF,PCOR
But what I need is something of the form,
rownames(coeffs, "Y PCHICK PBEEF PCOR")
which does not contain commas.
Any hints?
