EasyReg International

EasyReg (Easy Regression) conducts various econometric estimation and testing tasks on all 32bit Windows platforms (95 through Vista), simply by clicking the mouse. This software is created by Herman J. Bierens of Pennsylvania State University.


EasyReg is designed for use in empirical research, and for teaching econometrics. In the latter case the user can choose his or her own econometrics level.

What does EasyReg do?

EasyReg does most of the econometrics tasks available in competing commercial software, in particular:

and even more. Some of the listed software have additional features, though. EasyReg is mainly a point-and-click program, whereas some of the listed commercial software packages (in particular RATS and TSP) are programmable.

Data size limitations

All arrays in EasyReg are declared with variable dimensions. However, the number of observations is stored in an integer variable, which in Visual Basic 5 is limited to a maximum value of 32767. Consequently, if you try to import a data set with more than 32767 observations you will get an error message, and EasyReg will crash. On the other hand, such large data sets are rare in empirical econometrics. Therefore, in practice the amount of data that EasyReg can handle depends on the memory capacity of your computer.
