Terminology
In gretl parlance, a database is a (usually large) collection of
series that may be of mixed frequencies and observation ranges. The data are
stored in binary format, as single-precision «floats». You access such files
via gretl’s File/Databases menu. From there you can import
selected series into gretl’s workspace. Gretl databases have a .bin
filename suffix, and are accompanied by an index file (suffix .idx)
containing information on the series.
A gretl datafile, on the other hand, is a collection of series that
is homogeneous with respect to frequency and observation range (though
there may be missing values for some variables at some observations).
Such a file may be read directly into gretl’s workspace. Gretl
datafiles typically have a .gdt suffix; by default they
are in XML format, conforming to the Document Type Definition (DTD) given in
gretldata.dtd.
For further details, please see the gretl manual.
Крушение Третьего Рейха
Через три дня после свадьбы Гретл состоялась высадка в Нормандии . Социальная сцена в Бергхофе фактически закончилась 14 июля 1944 года, когда Гитлер уехал в свой военный штаб, чтобы никогда больше не возвращаться. 19 января 1945 года Гретль и Ева прибыли в рейхсканцелярию в Берлине, но 9 февраля уехали в Берхтесгаден. Позже Ева вернулась одна. 23 апреля она написала Гретл свое последнее письмо с просьбой уничтожить все ее деловые документы, но сохранить личную переписку или похоронить ее. Ни один из этих документов не обнаружен.
Гретль была беременна и все еще находилась в Бергхофе, когда ее муж был арестован за дезертирство 28 апреля 1945 года в квартире в Берлине, пропав без вести из фюрербункера . Первоначально, из уважения к Еве, Гитлер рассматривал возможность отдать Фегелейну приказ защищать Берлин. Однако, узнав о предложении Гиммлера сдаться западным союзникам, Гитлер приказал арестовать Гиммлера и расстрелять Фегелейна. Гитлер женился на Еве Браун рано утром 29 апреля. Днем 30 апреля 1945 года пара покончила жизнь самоубийством. 5 мая 1945 года в Оберзальцберге Гретль родила дочь, которую назвала Евой Барбарой в память о своей сестре. Ева Барбара покончила жизнь самоубийством в 1975 году, после того как ее парень погиб в автокатастрофе.

Processing Econometrics Data
Gretl is a Business software package developed by Allin Cottrell, Riccardo Lucchetti and the gretl team. The cross-platform, open-source software package is designed for econometric analysis.
Analysis For Statistics And Econometrics Data
Gretl is an acronym for Gnu Regression, Econometrics and Time-series Library. It is coded in C language and users are free to redistribute it, as well as add or modify the software package contents. Users still have to comply with the GNU General Public License (GPL) as stated by the Free Software Foundation.
Packaged With Forecasting Tools
Gretl is created to lighten the load of every statistician and econometrician. It has an easy to use interface with support to several languages commonly used today. The software package comes with a lot of estimator functions such as GMM; single-equation, least squares, maximum likelihood, and system methods. This allows inferring of an unknown parameter value plotted in a statistical model. Users are also provided with time series indexing methods like ARIMA, univariate GARCH-type models, Kalman filter, structural VARs and VECMs, unit-root and cointegration tests. This enables indexing data in time order. It includes limited dependent variables like interval regression, logit, models for count and duration data, probit, sample selection, and tobit. This allows estimating the connection between the limited dependent variable being observed and other variables requires methods with set parameters. The software package has panel-data estimators allow for consistent estimation of the observed explanatory variables’ effects as well as cross-section units. This includes GMM-based dynamic panel models, instrumental variables and probit. This software package can process output models like LaTeX files. The output models are plotted in an equation or tabular format.
Open Source Features
Gretl’s main advantage over other software package is its capacity to be integrated with several add-ons and contributed function packages made by other users. This will enrich everybody’s experience when analyzing data from statistics and econometrics. The software package is built with a custom, integrated scripting language called hansl, an acronym for Hansl’s A Neat Scripting Language. hansl is an interpreted scripting language that automates repetitive tasks so that users can easily make procedures implementing techniques and special functions that could be absent in gretl. Similar to standard scripting languages, it has data structures with conditionals and complex features, along with loops. It also natively supports matrices as primitive variable types. Some of the function packages and other add-ons for gretl are written in hansl. Other than hansl, it includes more programming tools as well as matrix operations.
Compatibility With Other Statistical Tools
To process statistics and econometrics easier, the software package has a GUI controller so that users can create fine-tuned Gnuplot graphs. Users can expect a more convenient facilitation of data and result exchange with other programming languages like GNU R, GNU, Julia, Octave, Ox, Python, and Stata. The software platform allows parallelization via MPI, as well as support for Mixed Data Sampling approach (MIDAS) mixed time-series frequencies and Library for Support Vector Machines (LIBSVM) machine learning library.
Contribuir al desarrollo de Gretl
¿Tiene Vd. alguna idea o código con el cual le gustaría contribuir al desarrollo de Gretl?
Si es así, estaríamos encantados en escucharle. Vd. probablemente debería unirse a la
lista de correo gretl-devel
(es una lista de bastante poco tráfico).
La única condición respecto al código que se incorpora a Gretl es que Vd. debe estar conforme en que aparezca bajo la
Licencia Pública General GNU (GPL), es decir,
Vd. debe de estar de acuerdo en que se distribuya el código fuente.
Como se ha mencionado más arriba, Gretl está escrito (principalmente) en el lenguaje de
programación C, el lenguaje más común en el mundo del software de código abierto.
Sin embargo, no todo el mundo se siente cómodo al escribir en C. Debe entender que esto no es
una barrera para contribuir a este proyecto con código o algoritmos. Si Vd. puede proporcionar un
algoritmo bien especificado para llevar a cabo alguna interesante tarea econométrica, probablemente
no nos será difícil reescribirlo en C o hacer que Gretl lo interprete. Esto incluye código en Fortran
o C++; código escrito en algún lenguaje de alto nivel para manipulación de matrices tal como Ox, Gauss,
Octave, Matlab o R; e incluso pseudo-código, es decir un algoritmo explicado explícitamente, paso a paso,
pero no escrito en ningún lenguaje de programación en concreto.

Penn World Table, PWT56 (cross-country macro panel data) |
||
|
Jones-Obstfeld Saving and Investment Data for 13 Countries |
||
|
NBER-CES/Census Manufacturing Industry Productivity Data, |
You should follow up the links in the first column above to get
full details on these data sets. I am in the process of assembling
my own notes on these packages; for the moment I have only done this
for the Penn World Table.
Penn World Table
PWT56 is a rich macroeconomic panel dataset, spanning 152 countries
over the years 1950 to 1992. The package for gretl comprises three
main data files:
-
pwt56.gdt: the entire pwt56. This dataset has many missing
observations. -
pwt56_60_89.gdt: A panel data set of 120 countries for
the 30 years 1960-89, containing 20 variables. This data set has no
missing observations. -
pwt56_1985.gdt: More data are available for 1985 than for
any other year, so I also made a pure cross-sectional data file for
all 152 countries for this year. This file has some missing
observations, but these will not be quite so difficult to deal with in
a cross section as in a panel data set.
The package includes full documentation and sample scripts to analyse
the data.
Ранний период жизни
Браун была младшей из трех дочерей школьного учителя Фридриха «Фрица» Брауна и швеи Франциски «Фанни» Кронбергер. Бросив среднюю школу в Медингене в возрасте 16 лет, она работала клерком в фотоателье у Генриха Хоффмана , официального фотографа нацистской партии , который также нанял ее сестру Еву. Гитлер предоставил сестрам квартиру с тремя спальнями в Мюнхене в августе 1935 года, а в следующем году виллу в Богенхаузене . Их отец был недоволен такой договоренностью и написал по этому поводу протест. Сестры были увлеченными фотографами; в 1943 году Гретл поступила в Баварскую государственную школу фотографии.

Contributing to gretl
Do you have ideas or code that you’d like to contribute to gretl? If so,
we’d be very pleased to hear from you. You should probably join the
gretl-devel mailing
list.
The most obvious way of contributing your expertise to gretl
development is by writing
a function
package (using gretl’s scripting language,
hansl).
You can see a listing of current packages
here.
A quick Guide
to producing function packages is available (thanks, Stefano Fachin!).
If by any chance you’re a C coder then contributions to the
underlying gretl library would also be welcome. The only
non-negotiable requirement on C code that can be contributed to
gretl is that you must be willing to have it appear under
the GNU General
Public License (GPL), that is, you must be comfortable with
having the source released.

Gretl’a katkıda bulunmak
Gretl’a katkı olarak sağlamak istediğiniz fikir veya kod mu var? Eğer öyleyse sizden haber almaktan büyük mutluluk duyarız. Bunun için gretl-devel eposta listesine (İngilizce, oldukça düşük hacimli) katılabilirsiniz.
Gretl’a katkı olarak verilebilecek kod için tek gereksinim, sizin bunu GNU Genel Kamu Lisansı (GPL) altında sağlama konusunda istekli olmanız, yani kaynağı özgür bırakma konusunda rahat olmanızdır.
Yukarıda söz edildiği gibi, gretl özgür, açık-kaynaklı yazılım dünyasındaki en yaygın dil olan C programlama dili ile (büyük ölçüde) yazılmıştır. Ancak, herkes C ile yazma konusunda yeterli değildir. O halde bilmelisiniz ki bu durum kod veya çözüm yolu katkısında bulunmak için bir engel oluşturmak zorunda değildir. Eğer ilginç bir ekonometrik görevi başaran iyi belirtilmiş bir çözüm yolu sağlayabilirseniz, bizler büyük olasılıkla bunu arayüzlendirebilir veya aşırı zorluk yaşamadan C dilinde yeniden yazabiliriz. Fortran veya C++ kodu; Ox, Gauss, Octave, Matlab veya R gibi yüksek-seviye dizey işleme dillerinde yazılmış kodlar; ve hatta sözde-kod, yani belli bir programlama dilinde olmayıp, adım adım, açık bir şekilde gösterilmiş çözüm yolları, olasılıklar arasındadır.
