GNU Regression, Econometrics and Time-series Library provides
a library which comprises various functions relating to econometric
estimation, a command-line client program and a GUI. The library is
based on the stand-alone command-line econometrics program ESL,
originally written by Ramu Ramanathan of the Department of Economics
at UC-San Diego. The interfaces offer several least-squares based
estimators. Besides reading data files in its own format it also
reads RATS 4 databases. It has a built-in spreadsheet for editing
data, and uses gnuplot for graphing. It can output regression results
in LaTeX format.
