new Kalman interface

For anyone interested in working with state space modela via gretl: 
please note that we have now replaced the documentation in chapter 30 
of the Gretl User's Guide with an account of the new (bundle-style) 
interface. We think the new code is now ready to roll, but if anyone 
is able to do some testing before the next release -- which should be 
in a week or so -- we'd be grateful.

The old Kalman interface is still available for now (but will likely 
be removed in the release following the next one). And you can find
the old doc at

http://gretl.sourceforge.net/papers/kalman_old.pdf

Drop-down menu issues

Linux Mint 17.3 MATE, -gretl- 2016c-git

I've noticed over the last several versions of -gretl- that I can no longer activate the drop-down menus in the results output window. I can fix it by clicking on the 'Windows' menu and then selecting 'Arrange', which sends all the windows to the north-west of my screen, but this is a bug, isn't it?

Once this is fixed, I want to film a new tutorial soon to post onto YT, but none of the screencasting tools I've experimented with (including Vokoscreen) works satisfactorily. Suggestions, please?

accents, line breaks

This is in response to Henrique Andrade's postings,
http://lists.wfu.edu/pipermail/gretl-users/2016-June/011883.html
http://lists.wfu.edu/pipermail/gretl-users/2016-June/011884.html

It turns out that these issues could be fixed without great difficulty 
-- see git and the current snapshots. We now intercept and modify "%s" 
string conversion specifiers for printf and sprintf so that numerical 
values indicating width and "precision" are taken to be in UTF-8 
characters rather than bytes.

Since email is liable to mangle this sort of thing, I'm attaching a 
little PDF file which illustrates "before" and "after".

As for extra line-breaks appearing in some contexts on Windows, this 
is to do with the Windows-specific business of opening files in text 
versus binary mode; I think it should be fixed now too.

something in between values() and aggregate()

Hi again,

I want to check a series for ties, meaning exact values that occur more 
than once in the series, and also get the respective counts of how many 
occurrences there are at each of these ties.

The function values() gives me information about the ties, as it drops 
repeated values. But it seems it doesn't have the counts.
The function aggregate() is very general, and so I think for a series y 
I could do:

matrix m = aggregate(y, y, mean)

Here the "mean" thing is just a redundant dummy entry, it could be 
anything from the allowed functions (see the doc for 'aggregate'). 
Another redundancy is the double entry of "y", the first "y" could also 
be any other existing series, it's just needed to satisfy the number 
(and position!) of arguments.
Then what I want to use are the first 2 cols of m: m[, 1:2].

So, is there a more elegant but still readable way to get the first two 
columns of:
aggregate(<anyseries>, y, <anyfunction>)

Thanks,
sven

Kendall's tau

Hi,

there are the options --spearman and --kendall for the 'corr' command. 
(And in the GUI, Model -> Robust estimation -> Rank correlation).

How to get the results of these computations, i.e. what is the 
function-based variant? The corr() function doesn't do this, according 
to the doc.

thanks,
sven

Printf & sprintf: problems with accented names

Dear Jack and Allin,

I found a problem with format specifiers and printf and sprintf.
Please take a look at the following example:

<hansl>
printf "start->%10s<-end\n", "aeiou"
printf "start->%10s<-end\n", "áéíóú"

string s1 = sprintf("start->%10s<-end\n", "aeiou")
string s2 = sprintf("start->%10s<-end\n", "áéíóú")
print s1 s2
<\hansl>

I believe Gretl is ignoring accented names when formating the output.

Best regards,
Henrique Andrade

Outfile and line breaks problem

Dear Allin and Jack,

I think Gretl is making something wrong regarding to line breaks :-(

Please take a look at the following script:

<hansl>
outfile " <at> dotdir/test1.txt" --write --quiet
loop i = 1..5 --quiet
    print "We all love Gretl!"
endloop
outfile --close

outfile " <at> dotdir/test2.txt" --write --quiet
string s1 = readfile(" <at> dotdir/test1.txt")
print s1
outfile --close

string s2 = readfile(" <at> dotdir/test2.txt")

printf "\n# String 1:\n%s\n# String 2:\n%s", s1, s2
<\hansl>

I think the strings 1 and 2 are the same, but s1 has CR LF line breaks
and s2 has CR CR LF line breaks. This behavior is breaking my script
that generates markdown file format documents (.md).

Best regards,
Henrique Andrade

How to Save the Results from "corr" command?

Hi there,

I am building a "rolling" correlation between two series, using a loop and smpl command. Given that, I'd like to know how can I save the results of the "corr" command...

Does anyone have any idea?

Thanks in advance,

"colname" and "rowname" after matrix functions

Dear Allin,

When I use matrix functions Gretl exhibits different behavior regarding column names and row names. Please take a look at the following script:

<hansl>
matrix Mat = {1, 2; 2, 1; 4, 1}
strings Cols = defarray("Col. 1", "Col. 2")
strings Rows = defarray("Row 1", "Row 2", "Row 3")
colnames(Mat, Cols)
rownames(Mat, Rows)

matrix msortbyMat = msortby(Mat, 2)
matrix mreverseMat = mreverse(Mat)

print Mat
print msortbyMat
print mreverseMat
</hansl>

The msortby function keeps the names but the mreverse doesn't. Is this the expected behavior?

Best regards,
Henrique Andrade

Sorry for cross-posting, but this is very very important.

In the past few weeks, we have been working on a substantial rewrite of
the hansl interface to state space models.

The underlying computational engine is pretty much the same as before, but
the way a user can access it via hansl scripting has been completely
redesigned. The work isn't finished yet, but we're quite near completion
and we'll publish soon a document explaining the revised interface.

In fact, we're quite impatient to make the change for two reasons: (a) the
new style is WAY better than the old one under all respects: efficiency,
maintainability, generality, intuitiveness, you name it. (b) keeping both
approaches functioning at once is possible (in the git/snapshot version
you get just that, in fact), but very costly. Therefore, we'd like to drop
the old syntax as soon as possible.

Of course I hear you, Sven. This would be a MASSIVE backward-incompatible
change, much bigger than any we had in the whole history of the project.

For this reason, we'd like to have an idea of how many people out there
are using the "kalman" command in a "production" environment; that is,
hansl scripts that HAVE TO WORK. If it's just a few, we can arrange a
somewhat "ad personam" migration strategy. If there are hundreds of such
cases (but I doubt it), we'll have to find another solution.

So please speak up! The sooner the better.

I was teaching State Space Models some years ago, and you already know I
prepared some packages (BSMestim LLTestim) when there was still no
native commands for the Kalman filter in gretl. I have checked the
native commands some times, but I have not used them seriously. So don't
worry about me, backward incompatibilites will not cause me any problem.
I look forward to the changes and I am sure that the improvements in
these commands will contribute to facilitate the use of state-space
models in gretl.

I'd love to see the new state space environment.

The old was good, but too complex to manage.

I guess I'm sounding repetitive, but with gnuplot 5 and using the
compact inline data specification that you managed to get into gnuplot
it doesn't strike me as very difficult. It works for me when I do:

$testdata using 1:3:4 title "bands" w filledcurve

of course after having put the data in a suitable "$testdata" block.

But still, a nice feature of course.

thanks,
sven
