Hello. I'm new to gretl and I'm trying to create a simple script that will,
for instance, seasonally adjust all variables. And I've run into troubles.
So...
1. how do I generate variable *variable names* to genr? for instance, I want
to call each detrended variable "sa_" & the original variable name
2. how do I pass the parameter to deseas()? deseas(gdp) works fine, but
deseas(varname(4)) doesn't (assuming varname(4)="gdp", varname returns a
string and deseas doesn't work that way. I also tried looping through a list
of all the variables, but the same error of erroneous argument type is
brought up by deseas().
Thanks!!

Asymmetric Cointegration Test with TAR
by Thomas Volscho
Has anyone written a script for doing a "grid research" for determining the threshold value for a TAR to be used as a test of asymmetric cointegration? Enders has something in his RATS programming guide and I was wondering if anyone has written anything for GRETL.
Thanks in advance!

Asymmetric Cointegration tests

Dear List,
Has anyone written a script that would determine the threshold for an asymmetric cointegration test?

about distribution function display
by Dorian Litvine
Dear Gretl users,
Do you know how to describe the « estimated logit distribution » of a
binary variable (dependent)? which means presenting the distribution
function 1-F(X) of the probability of observing a given value of the
dependent binary variable according to the values of a polynomial
variable (independent) ?
Thank you very much.

operate on all variables
by Santiago Afonso
Hello. I'm new to gretl and I'm trying to create a simple script that will,
for instance, seasonally adjust all variables. And I've run into troubles.
So...
1. how do I generate variable *variable names* to genr? for instance, I want
to call each detrended variable "sa_" & the original variable name
2. how do I pass the parameter to deseas()? deseas(gdp) works fine, but
deseas(varname(4)) doesn't (assuming varname(4)="gdp", varname returns a
string and deseas doesn't work that way. I also tried looping through a list
of all the variables, but the same error of erroneous argument type is
brought up by deseas().
Thanks!!

randgen question
by Talha Yalta
I am trying to perpare a ML tutorial where there are T balls in a bag
with a ratio of P=0.75 black balls and there will be 250 independent
trials where 0<X<10 randomly chosen balls from the bag will show Y
blacks.
I create a new data set with 250 observations and create X with genr X
= floor(randgen(u,0,11)
After this, however, the command genr Y = randgen(b,0.75,X) does not work.
Any suggestions?
Also a few bugs/problems that I have discovered along the way:
1)- Creating a binomial random does not work from the GUI. After
creating a cross-sectional 50, Add --> Random variable and selecting
binomial, I enter 0.5 10 and xx in the three boxes and clicking OK
gives an empty error dialog box.
2)- I open the scalars window and if I first click on the name column,
enter something and then click on the value column (or an empty pert
of the window) I get the error: 'cc' -- no numeric conversion
performed!
3)- If I do the above twice three times etc., the error message is
also repeated twice, three times etc. (as rows within a single error
window).
4)- If I keep pressing the add button, the scalars window will be
filled with epmty rows of empty scalars with no x buttons to erase
them.
5)- With the first row being empty, if I enter a value in the second
row and click on its name cell, there is an error message in the
console:
*** gretl_scalar_add: there's already a '' at level 0 (1,79769313486232e+308)
6)- Because the scalars window is now modal in the cvs, everything is
frozen when it remains open. I cannot even quit gretl without first
closing the scalars window. It is as if the program has crashed.
Similarly, after running a ml estimation from the GUI, the scalars
window is opened automatically but since everything is frozen, it is
not possible to scroll down the model estimation window even. I really
hope the syncronization code solving these problems will be added
soon.
Best regards
Talha

dummy variables
by Data Analytics Corp.
Hi,
I have two question on how to create dummy variables. Suppose...
1. I have a time series of annual data, say from 1970 to 2000. How
do I create a dummy for the period 1975-1980 (1 for this period, 0
otherwise)?
2. I have cross-sectional data by states. How do I create a dummy
for the southern region where I know the states in that region?
Thanks,
Walt

Problem with Gretl Session
by Henrique
Dear Gretl Community,
When I change a variable attribute (Variable -> Edit attributes) I'm not
able to save this modification in my session file (File -> Session files -
Save session). The problem occurs even if I change the name of the variable.

Problem with graphs
by Henrique
Dear Gretl community,
When I try to plot a graph (View -> Graph specified vars -> Time series
plot) gretl shows me the following error message:
dyld: Library not loaded: /usr/local/lib/libreadline.5.2.dylib
Referenced from: /Applications/Gretl.app/Contents/Resources/bin/gnuplot
Reason: image not found
I'm using Gretl (snapshot 2009-11-04) on Mac (Snow Leopard). With the
snapshot 2009-10-31 this problem doesn't occur.
Best,
