Re: iPad download
by John C Frain
On an Android phone or tablet and on an Amazon Fire tablet one can install Userland which offers a choice of Linux systems. Gretl 2016d is available as a package in this system. The gretl graphic interface does not fit well on a mobile phone but it is just about usable on a 10 inch Fire tablet. I presume that one might be able to use the command line. I have used the octave command line in Userland for some calculations.

That is not possible.
Gretl is a computer only software. There are a lot of dependencies libraries that are not available in mobile (tablet, smartphones) devices.

Hi everybody,
How can I download Gretl for iPad?
Thanks in advance

logistic regression model fit goodness test
by aktas.yusuf.585858＠gmail.com
Hello
I have a few questions I've just started using GRETL.
1-GRETL program, the logistic regression (binary) model for the goodness of fit test hosmer-lemoshov statistic is not the cause of linear regression F statistic value.
2-Doesn't the program create logistic regression modeling of categorical sub-divisions of explanatory variables (eg 1-elementary, 2-high school, 3-associate…)?
3-Can't non-parametric tests be tested?
Thank you.

Data labels disappear when choosing Freeze Data Labels
by Peter H. Lemieux
Kubuntu 19.10
Gretl 2019c for Linux x86-64
Build date 2019-07-03
If I swipe across a chart my data labels appear as expected. However
when I choose Freeze Data Labels from the context menu, the labels all
disappear. This is not the behavior I observed in previous versions,
nor obviously the expected behavior.
2019c is the most recent version of gretl in the Ubuntu repositories. If
I build a version from the current source code, will it fix this
problem? Otherwise I might have to downgrade to an earlier version that
freezes the labels correctly.
Thanks!

Save session using a script
by Filipe Rodrigues da Costa
Dear Gretl Users,
I have a long script to work with data. I was wondering if there's a simple way of adding a few lines of code to save the session. It is easy to save as .gdt but I cannot find a way of doing it as .gretl. It would be something similar to:
*<hansl>**
*
*store " /home/user/docs/myfile.gdt"**
*
*</hansl>*
The idea is to keep not only the dataset but also the work done on it. That's why I was looking for .gretl instead.
Thanks in advance.

Hi Victor,
use the smpl command with the --no-missing (or --balanced) option before
to restrict your datatset
<script>
list L = Y X1 X2
smpl --no-missing L
# Run your panel unit-root test
</script>
Best,

Re: functions and loops
by Alecos Papadopoulos
Good afternoon.
I need to find the argmax (the mode) of a conditional density, for many
different values of the conditioning variable. For a single value of the
conditioning series variable "res", the following block appears to work
(pre-accompanied by the generation of the various inputs needed)
<hansl>
scalar ressc = res[1]
function scalar udensity (const scalar sv, const scalar thu, matrix
param, scalar ressc)
scalar densu = -0.5*param[1,1]^2/sv^2 - ressc*param[1,1]/sv^2
-param[1,1]/thu + log(1-exp(-param[1,1]/thu)) #this is the conditional
density of the "param"
return densu
end function
matrix modeu[1,1] = 0.1 #intiial value for the unknown value
(argmax) we are seeking
densval = BFGScmax(&modeu, bounds, udensity(sv, thu, modeu, ressc))
</hansl>
The function above uses the value that the conditioning variable "res"
has at observation #1, and then BFGScmax finds the argmax given this
value of "res". If I then set scalar ressc = res[2], I can get what I
need given the value that the conditioning variable takes in observation
2, etc.
I was unsuccessful to transform the above script into a repetitive one,
starting with the fact that I cannot define a function inside a loop, as
Gretl informs me. I tried various other ways to essentially loop over a
command like BFGScmax that requires as input a function that must change
at each instance of the loop, but all failed.
Is there a way to do this?

Multiple instances on a Mac?
by Riccardo (Jack) Lucchetti
Is it possible to have more than one instance of gretl running
simultaneously on OSX?
I have a student who needed to keep two datasets open at the same time;
the way I normally do this on Linux (and I gather, I would on Windows) is
opening more that one instance of gretl, but we found no ways to get this
done on her Mac.
Any advice?

Gretl crashed again while opening data series with data string that gretl didn't like.
by Fred Engst
Sorry, Allin, more work for you.
When I opened excel file downloaded from FRED called usrec.xls
window opened asking import from c1 r1, so I clicked OK,
it crashed.
This is repeatable.
I found out that the reason for crash has to do with the headers from the FRED file that had a lot of information before the real data starts on row 11.
After deleting the first 10 rows, if I save the file
1. in csv format, it will be OK. The dates are ok too.
2. in xlsx format, it will not crash, but the dates were not read-in. I had to set the dates myself.
3. In xls format, I get this message:
Expected numeric data, found string:
"1854-12-01" at row 2, column 1
Perhaps you need to adjust the starting column or row?
So, it shouldn’t crash just because I imported the wrong kind of data.
Furthermore, there is some kind of inconsistency between the different file format when gretl deciding on the date value.
Thanks in advance for all your work.
Fred
