Eviews' files
by Claudio Shikida (敷田治誠 クラウジオ)
Hello to all,
Just a question. I don't have Eviews installed in my computer. However,
sometimes people send me eviews' files (wf1). After installing the last
version of gretl, I couldn't open wf'1 files anymore. The error message
asks for a libxml2.dll. I don't know if this is precise or how to download
a safe version of this library.
Any suggestions would be welcome,
thanks!
Obrigado / Thanks for your time and attention.

sorry, learning hansl question
by Tim Nall
If you can figure out the iffy psuedo-psuedocode below, I'm trying to
run 1 ols regression over 4 different date ranges (so total 4
regressions) with 1 dependnet variable and 1 independant variable..
but I want to run a kpss test on both the depvar and indvar before
doing the regression for each date range, then utilize either the
variable or its fiorst-differenced version depending on the results of
the kpss (at 5%, hopefully).
Can this be done in hansl?
start_yr = 1855 1860 1865 1870
end_yr = 1894 1899 1904 1909
## get MyDepVar and myIndVar from file, then
for i in start_yr, end_yr
smpl start_yr end_yr
kpss 3 myDepVar ## and capture results
if stationary = True:
tempDepVar = MyDepVar
else:
tempDepVar = d_MyDepvar
kpss 3 myIndVar ## and capture results
if stationary = True:
tempIndVar = myIndVar
else:
tempIndVar = d_myIndVar
ols tempDepVar tempIndVar

hansl function similar to armax?
by Tim Nall
Is there a way to estimate the best ARIMA model within hansl? Granted
I could just generate a half dozen or so and compare selection
criteria, but is there a more elegant way? Tks

Time series interpolation
by Huffelpuff
Hi,
I'm new to gretl, so forgive my ignorance. I'm aware that gretl provides
forecasting functionality, but I'm interested in using any of the
time-series models in gretl (AR, ARIMA, GARCH, etc) to interpolate a
section of unknown data. If I have something like this:
Year Stock value
1950 215
1951 220
1952 200
1953 195
Then it is easy in gretl to predict the following years (1954, 1955, and
so forth). But if I have something like this:
Year Stock value
1950 215
1951 220
1952 200
1953 195
1956 190
1957 185
1958 170
1959 150
I then want to "predict" (or technically interpolate) the values for the
years 1954 and 1955 (the stock value will probably be something between
195 and 190). Is this possible with gretl? If so, how?

Time series prediction
by Narandra Dashora
Give time series a numerical value such as 1 for 1950 and so on , But Give
1956 the value 7 . This will give you regression equation
The put in the value of X. The solution of your problem may be by using
Time Stock 1 215 2 220 3 200 4 195 7 190 8 185 9 170 10 150

set multiplot
by Javier Sansa
When plotting graphs using gnuplot is it possible using the gnuplot
command set multiplot in a script in order to plot several charts together?
I have tried using it and I keep getting an error message. If it is
possible, could you provide me a short script to see how it is done?
Thanks in advance,
