It is coded in C language and users are free to redistribute it, as well as add or modify the software package contents.

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 vretl as GMM; single-equation, least squares, maximum likelihood, and system methods.

This allows inferring of an unknown parameter value plotted in a statistical model. 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. 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.

The software package is built with a custom, integrated scripting language called hansl, an acronym for Hansl’s A Neat Scripting Language. Similar to standard scripting languages, it has data structures with conditionals and complex features, along gertl 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. To process statistics and econometrics easier, the software package has a Tretl controller so that users can create fine-tuned Gnuplot graphs.

At the prompts, accept the installation defaults and the program will then create an icon on your desktop for Gretl. Double-click on the desktop icon to start the program.

III. Preparing and Importing Excel Data Files

The 'recommended' way to analyze data using the Gretl program is to first create an Excel workbook, and then 'import' the data into the program.

NOTE: Like most statistical programs, importing data works best when the data have been saved as MS Excel comma delimited file (csv) worksheets.

A. To create and save data into a MS Excel comma delimited file (csv) worksheets:

i. Start the MS-Excel program and either (a) type in the data to a blank worksheet or (b) open a saved Excel file and click on the worksheet containing the data to be imported.
ii. Make sure that each column of data is headed by a variable name that (a) begins with a letter and (b) is no longer than eight contiguous characters in length.
iii. Make sure that, aside from the column headings, all of the data consists of numbers. Gretl will ignore alphanumeric values so be sure to first convert categorical variables (e.g., yes, no) into numerical variables (e.g., 1, 0). NOTE: you can use Excel's *Edit* Replace* to do the conversion.
iv. Delete all worksheets except the one containing the data
v. To save the data, click on * File * Save As * and then type in a file name and click on MS Excel Comma Delimited File (csv) as the file type.

B. To import the saved Excel worksheet into the Gretl program:

Start Gretl and click on * File * Open Data * User File *, change the file type (bottom right) to CSV, and then point to the folder containing the data. Next espond to the query on whether the data is undated or time-series or panel. If the data is either time-series or panel, you'll have to enter additional information regarding how the data is measured, i.e., the starting date for the data, the number of time-periods, etc. After you have imported the data, double-click on the variable names to check that the program processed the data correctly.

IV. Descriptive Statistics and Simple Plots

A. To obtain Descriptive Statistics, highlight the variable names that you want statistics for and then click on * View * Summary Statistics * OK *. To obtain correlation coefficients, click on * View * Correlation Matrix * *OK*.

B. To obtain Simple Bivariate Plots, click * View * Graph specified vars * X-Y scatter * and then identify the variables you want to plot on the X and Y axes.

V. Ordinary Least Squares Regression

To run an Ordinary Least Squares (OLS) regression in the Gretl program, click on * Model * * Ordinary Least Squares *, identify the dependent variable and independent variables, and then click on * OK *. The * Analysis * tab will generate additional statistics including predicted values and residuals and confidence intervals for the coefficients. The * Graphs * tab will generate differing plots of the residuals.

VI. Testing and Correcting for Serial (Auto) Correlation

Gretl will generate the Durbin Watson Statistic after an ordinary least squares regression is estimated. The results for the Breusch-Godfrey test for autocorrelation can also be obtained by clicking on * Tests * Autocorrelation * and entering the desired number of lags. To estimate Generalized Least Squares (GLS) corrected results, click on * Model * Times Series *, select the estimation method (e.g., Autoregressive Estimation) and then identify the dependent and independent variables and the number of AR term lags (usually 1). To estimate Newey-West corrected standard error results, run an Ordinary Least Squares (OLS) regression but also click on * Robust standard errors * Configure * and on the * HCCE * tab make sure that * HAC * is highlighted for * time series data *.

VII. Testing and Correcting for Heteroskedasticity

Filmorago For Pc Download

After an ordinary least squares regression is estimated, you can test for heteroskedasticity by clicking on * Tests * Heteroskedasticity * and entering the desired test, e.g., White Test. To estimate corrected results, run an Ordinary Least Squares regression but also click on * Robust standard errors * Configure * and on the * HCCE * tab make sure that the desired correction method (e.g., HC1) is highlighted for * cross sectional data *.

VIII. Logit Regression Models

To generate a logit regression model on a binary dummy (1,0) dependent variable, click on *Model* * Limited Dependent Variable * Logit * Binary *, and then identify the dependent and independent variables. Gretl will then generate logit results, including transformed coefficients measuring the marginal impacts of the explainers evaluated at their mean values.

IX. Creating New Variables

New variables can be created out of existing ones by clicking on * Add * New Variable * and then typing in the formula for computing the new variable. For example if you wanted to multiple X1 times X2 to create an interactive variable named X1X2, then click on * Add * New Variable * and type in the formula box X1X2 = X1 * X2 . Make sure that if the variable names are capitalized, your formula includes capitalized names.

X. Subsamples

To select subsamples of the data set, click on * Sample * and * Set Range * and then define the range of observations that you want to include in the analyses that will follow. You can also use the * Sample * command to include a random sample of observations or to define expressions that will select/reject those cases that conform to the expression.

XI. Panel Data Regressions

To analyze panel data in the Gretl program, click on * Model * * Panel * * Fixed or Random Effects*, identify the dependent variable and independent variables and the model you wish to estimate, indicate whether you want time dummies included, and then click on * OK *. The * Tests * tab will generate additional statistics including tests for heteroskedasticity and serial correlation.

XII. Saving Projects

Gretl Download Mac Download

If you want to save an Gretl session for future analysis, and want to avoid re-importing the Excel data worksheet and recreating any data transformations that you've already done, then you must get Gretl to save your project. To do so, click on * File * Save Data *, point to the folder where you want the project saved, and name the project. Then you can reopen the project by starting the Gretl program, clicking on * File * Open Data * User File *, and then entering the saved project's name. Gretl will recreate all of the variables that were available at the time the project was saved.
