Hi everyone,
My name is Juan Pablo de Botton and I am developing a simple function (it is an
autocorrelation test) to share with the Gretl community in the near future. The statistic
has its own distribution so, in order to do the test, I need to insert a complete
statistical table that depends on the number of the observations and independent variables
you use in your regression. Since I have little experience in hansl programming, I was
wondering if there is a simple way to this. My first idea was to 1) insert all the values
in excel, 2) import them to gretl and, finally, 3) define that matrix in my script. The
function should be available to everyone so I don't know if this a good way to do it.
By the way, I'm new in hansl programming so any advice is welcome.
Thank you in advance for your help.
Sincerely, Juan Pablo de Botton Falcón.

Hi Juan,
I would skip steps 1 and 2. Just paste the values into the script file
and add 'matrix whatever = {' at the beginning and '}' at the end. Of
course, maybe you still need to add commas and semicolons in the right
places as row/column separators, but to do that I would actually
recommend a good text editor and some search&replace operations. (This
may also work directly in gretl's script editor, it depends.)
thanks,
sven

You may solve your problem by inserting the matrix, as Sven told you,
but dependind on the length
of the table you may reach the maximum length of line that gretl allows
(I don't remember now which it is).
A solution to this may be to insert the matrix row by row as in
matrix A={ -4.783526, -10.791375, -2256.893594, 93988.917323,
-4.795490, 952.835421, -32332.118197, 1.080773, -163.771987,
5047.690735, -0.053176, 8.181509, -248.416160, 4.734905, -145.551142,
-2847.941248, 0.024084 }
matrix A = A | {-4.570586, -10.520416, -1484.742149, 55861.734787,
-2.148871, 669.822179, -22270.746312, 0.606490, -119.336030,
3717.493047, -0.029792, 5.961770, -186.435210, 4.877938, -199.560485,
2128.738925, 0.015769 }
matrix A = A | {-4.315270, -9.521437, -1000.988718, 34255.592830,
-0.452878, 301.383083, -9213.315900, 0.371466, -55.669731, 1380.753501,
-0.020087, 2.606423, -59.777246, 4.526608, -157.399959, 2658.138055,
0.009907 }
... etc
I would recommend this if you have only one table and it is not very
big, but in the other cases probably it would be better
to put the matrix in a different file (using the command 'mwrite' ) and
call it from your script with 'mread'.
