Re: cross-tabulation without original raw data
Hi,
Is there any possibility of performing a cross-tabulation in gretl when
you only have
aggregated frequencies (I'm thinking of something analogous to Stata's
"tabi" command )?

Hello
I am having problems while running the runs test in levels, since the
number of runs (R) in the variable 'c_cemento'is always equal to 1 and
therefore the p value is always very low thus rejecting the null
hypothesis of randomness.
This problem does not appear when the test is run over the
first-difference series.
Thanks and best regards

This is normal if c_cemento is always positive. The runs test is based
on the
number of positive runs and negative runs, and tests randomness around
the
zero value. If all numbers are positive, there is only one run.
(See for example http://en.wikipedia.org/wiki/Wald-Wolfowitz_runs_test )

El Monday 16 Ma> Hello.I'm trying to write a script computing recursive residuals.
You're probably familiar with the concept how to obtain such a
residual: after estimating model for (n+1) observations (with dummy
variable equals 1 for observation number (n+1)) t-value for dummy
variable is multiplied by standard error of residuals. Unfortunately
something is
wrong.
I see no problem. The output I obtained is in the attachment.

Hello,
when I try to generate a xy-plot with the "--loess-fit" option using
the loop command
foreach i 6 10 100
gnuplot hph_$i hpwa_lab_$i --loess-fit --output=hp_h_wa_lab_$i.eps
endloop
the compiled files will be corrupted. For the other "fit"-options it
works well.
Is there a reason for this?
Best,
Artur

Yes ;-) The file were not actually corrupted, they were just
plain text gnuplot command files, not EPS. The trouble is that
when you select the loess plot option a special graphing function
is called, and that function was not getting the message that a
specific output format was wanted.
This is now fixed in CVS; I'll put up a fixed Windows snapshot
shortly.
Allin.

hi
I am trying to learn how to use the scripting interface - is there any
trainDoes anyone have any tips about getting started? I am trying to do basic
things like cleaning up a sample, getting descriptive stats and running
some regressions and even though I can do all of this through the GUI I
would like to get familiar with the console.
thanks.
