GNUPlot Question
by Logan Kelly
Hello,
This is a GNUPlot question, so feel free to indicate it is off topic. Is there a replacement for the command
set termoption dashed
in the version of GNUPlot packaged with the current snapshot?
Thanks,
Logan

loop
by Gmail
I've got a big issue to solve. I must implement an event study on a sample
of 100 firms.
In order to avoid to implement 100 regressions I try to use a loop:
"list ylist = 1 3 5 7 9 \
11 13 15 17 19 \
21 23 25 27 29 \
31 33 35 37 39 \
41 43 45 47 49 \
51 53 55 57 59 \
61 63 65 67 69 \
71 73 75 77 79 \
81 83 85 87 89 \
91 93 95 97 99 \
101 103 105 107 109 \
111 113 115 117 119 \
121 123 125 127 129 \
131 133 135 137 139 \
141 143 145 147 149 \
151 153 155 157 159 \
161 163 165 167 169 \
171 173 175 177 179 \
181 183 185 187 189 \
191 193 195
list xlist = 2 4 6 8 \
10 12 14 16 18 \
20 22 24 26 28 \
30 32 34 36 38 \
40 42 44 46 48 \
50 52 54 56 58 \
60 62 64 66 68 \
70 72 74 76 78 \
80 82 84 86 88 \
90 92 94 96 98 \
100 102 104 106 108 \
110 112 114 116 118 \
120 122 124 126 128 \
130 132 134 136 138 \
140 142 144 146 148 \
150 152 154 156 158 \
160 162 164 166 168 \
170 172 174 176 178 \
180 182 184 186 188 \
190 192 194 196
loop foreach i ylist --progressive
loop foreach j xlist --progressive
ols ylist.$i const xlist.$j
genr alpha = $coeff(0)
genr beta = $coeff(xlist.$j)
store vectors.gdt alpha beta
endloop
endloop
open vectors.gdt"
ylist and xlist are the lists that contain my independent variables.
Unfortunately, such code regress the first dependent variable on the other
100, then the second on the same 100 and so on and so forth.
How I can write a loop that only regress the variable 1 on the variable 2,
the variable 3 on the 4 etc?
How I can store the coefficients?

Re: [Gretl-users] Problem with Non-interactive in R-script
by George Matysiak
The only such directory I have is C:\Users\George\AppData\Roaming\gretl.
There is only Rout file there, being *gretl.Rprofile.Rout*.
Not sure if it's relevant, when doing a listing of directories, only
the *C:|Users|George
*sub-directory was listed/visible, and I have to type in and add the*
/AppData/Roaming/gretl *bit in order to get to this sub-directory and see
the contents.

yahoo_get: slow downloading
by guido giaume
Dear group
from a coupe of weeks - after updating my ubuntu 16 - I experienced
very often significant delay while getting data from yahoo.
Gretl windows "freeze" of if you prefere became grey for minutes (also
dozens).
Before the same download was made in seconds, much more less than one
minute.
Here my code
-------------------------------------------------------
# Apro un set di 100 giornate con
nulldata 100
# 5 rilevazioni settimanali che iniziano il 1 marzo 2016 e indico che è
una serie temporale
setobs 5 2016-06-01 --time-series
# chiama la funzione yahoo_get
include yahoo_get.gfn
# scarico i titoli
loop foreach i A2A.MI ATL.MI AZM.MI BMED.MI BMPS.MI BP.MI BPE.MI
A=yahoo_full("$i")
endloop
Please note i cutted the titles list: they are normally more than 50
and less 100, because i am interested in behaviour of the components of
market indexes.
-------------------------------------------------------
I dont know how to handle this situation because I'm not shure if
a) there is a problem in my line, but I dont think: tests and others
activities are ok.
b) there was an unsaid change in yahoo's download policy. Maybe they
decided to slow down the data rate (IE reducing the band).
c) Yahoo has some problems not yet solved.
d) May be, after upgrading, appened some modest conflict between the OS
and yahoo_get;
SO i ask if somebody can give me a suggestion how to handle this or if
you too have experienced some strong delay in the next weeks.
Best

Re: [Gretl-users] Problem with Non-interactive in R-script
by George Matysiak
Just an update. I reinstalled* gretl* and attempted to run the R-script
again. This time the message was
*"Can't open C:\Users\User\AppData\Roaming\gretl\R.out for reading".*
*"In God we trust, all others bring data."*

Re: [Gretl-users] Unable to access R in Non-interactive
by George Matysiak
I receive the following message when I try to access R for a *Non-interactive
(just get output)* session via the R-Script screen *"External command
failed*". In the preferences *Path to R.exe *I have "C:\Program
Files\R\R-3.3.1\bin\x64\R.exe". It all works fine when I access Rstudio in
the *Interactive R session.* Are there any other settings I need? Thanks.

deleting variables
by Summers, Peter
Hi all,
I've got a script that generates a bunch of auxiliary series that I don't want to keep in the dataset, so I put "delete thislist thatlist (etc.)" as the last line in the script. When I run it, I get a message (in the output) saying no series were deleted. When I try to delete them manually, I get an error saying "Cannot delete (whatever): variable is in use." However if I reload the dataset, the extra series are gone, so they're being deleted somehow.
Thoughts welcome...

Gretl 2016c: modtest --white
by Pedro Bação
Hello,
To replicate Greene's example 9.3 (heteroskedasticity tests), in Gretl I
run the script:
open TableF9-1.txt
square Income
smpl Avgexp>0 --restrict
ols Avgexp const Age Income sq_Income Ownrent
modtest --white
modtest --white-nocross
With Gretl 1.9.11, everything goes fine: Gretl manages to drop the various
combinations that are redundant in the auxiliary regression and prints the
expected results.
When I use Gretl 2016c (Lubuntu 16.04), both versions of the White test
fail with the message "Exact or near collinearity encountered". Am I doing
something wrong in Gretl 2016c, or has a bug creeped into modtest?
Thanks,
Pedro
