EasyReg International 2007-2008
Previous versions of EasyReg
Current and future versions of EasyReg
Differences between the versions April 2, 2006, and April 1,
2007:
- The main difference with the previous version is that all the menus are now
fully rescalable, and that wide-screen monitors are now supported. Moreover,
numerous cosmetic and other non-essential bugs have been repaired, and the
upgrade procedures have been improved.
- A new module has been added which allows you to create two and three-dimensional
plots from files.
- The module COINTJ which conducts Johansen's cointegration analysis now allows
you to test the joint significance of the VECM parameters, except the parameters
of the cointegrating vector(s). The guided tour involved has been upgraded and
extended accordingly.
- The miscellaneous modules are no longer included in the EasyReg setup; they can
be downloaded separately.
- Finally, all the guided tours have been redesigned. The new guided tours can
be viewed online.
Differences between the versions April 1, 2007, and September 12,
2007:
- April 7, 2007:
The module DATATAB which tabulates selected data has now the option to create
data files in EasyReg space delimited text format.
- April 10, 2007:
The EasyReg upgrade modules have been upgraded once more.
- April 13, 2007:
When you run the EasyReg main module EASYREG.EXE from CD or a network server,
the network start-up module EASYREGN.EXE should be activated automatically, but this
did not work. It does now.
- April 16, 2007:
A nonessential bug in the Wald test option of the "What to do next?" module has been
repaired.
- July 2007:
If you have downloaded and installed EasyReg before August 22, 2007,
the WWW menu items related to the Penn State and EasyReg web sites may no
longer work, because the URL of the server has changed. To fix this problem, do
the following.
The EasyReg folder contains a text file URLHJB.TXT with the (former) URL of my web site:
- "http://grizzly.la.psu.edu/~hbierens/"
Open URLHJB.TXT in Notepad and change this URL to:
- "http://econ.la.psu.edu/~hbierens/"
Alternatively, run ERIPATCH1.EXE
(See Upgrade EasyReg to the current version),
because this self-extracting Winzip file now
also includes a new version of URLHJB.TXT.
- August 22, 2007:
One of the build-in critical values of the Johansen's lambda-max test was incorrect (the 5% critical value in Table 5).
This bug has been repaired. Thanks to Marcel Priebsch for pointing this problem out
to me.
- August 31, 2007:
The EasyReg mirror site in Poland is no longer available. Therefore,
the link involved in the WWW menu has been removed.
Upgrade EasyReg to the current version
Note that EasyReg can also be upgraded to the current version via the
EasyReg menu item "WWW > Upgrade EasyReg to the latest version."
However, before you use this option, open
This self-extracting WinZip file extracts the latest versions of the file EASYREG.EXE
and the upgrade modules to the default EasyReg folder
c:\Program Files\EasyReg International.
Upgrades not yet included in the current version
- October 28, 2007:
The menu items regarding running EasyReg stand-alone from CD
have been moved to the Tools menu. Moreover, the Windows system files
are no longer copied to the EasyReg folder, but instead to a new folder,
"CopyEasyRegToCD", together with the entire contents of the EasyReg folder.
Furthermore, the last item in the help file (HELP.HTM) has been adjusted
accordingly. The Help menu now opens HELP.HTM directly.
- October 30, 2007:
The change made on October 28 also created a bug: Running EasyReg
from CD resulted in an error message. This bug has been repaired,
and EasyReg now runs from CD without problems.
- December 12, 2007:
The file FRACTIONS.PDF, which explains how to estimate a model with a
fraction as dependent variable, has been extended.
- February 22, 2008:
- The module DATAART which creates artificial data has been redesigned
and extended with Binomial Probit/Logit, Negative Binomial Probit/Logit
and Poisson data.
- Due to this extension of module DATAART I now have been able to test
the Binomial Probit, Negative Binomial Probit and Ordered Probit options
in the discrete dependent variable module LIMDEP. These options did not
work properly and have therefore been removed. The menu window of LIMDEP
has been redesigned. The guided tour involved has been adjusted accordingly.
- It appears that occasionally the EasyReg installer changes the date of
some files, which prevents them from upgrading. Therefore the EasyReg
upgrade module ERIUPGRADE now also checks for files with a later date than
the latest versions.
- Moreover, on the upgrade web pages generated by the EasyReg upgrade
modules the files that remain to be downloaded are now listed first.
The modules involved are COPYNEWER and COPYNEWERTOURS.
- February 23, 2008:
- At the novice econometrics level module OLS showed the variance matrices
and the information criteria. Now it does no longer.
- A new option has been added in module NEXTMENU for OLS regressions:
Manual forecasting. With this option you can input values for the
explanatory variables to forecasts the corresponding value of the
dependent variable, and endow it with confidence intervals. This option
is motivated by the undergraduate forecasting
course I am teaching.
- February 25, 2008:
- A non-essential bug in module DATAART has been fixed.
Planned future releases
- Double-censored Tobit models
- A user-defined functions building module which will
enable more efficient and flexible programming of the models in the user-defined
nonlinear models modules ML, NLLS and NLGMM.
- Allowing for sample sizes over 32,767 observations. This maximum is due to the
maximum integer value in Visual Basic. However, this is going to be a major
operation, affecting almost all modules.
- Robust M-estimation according to the approach in:
- Bierens, H.J. (1981), Robust Methods and Asymptotic Theory in Nonlinear
Econometrics, Springer Verlag.
- Anything else point-and-click that E-Views does and EasyReg does not,
which is not much.
