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. </longdescription> <use> <flag name="R">Enable support for <pkg>dev-lang/R</pkg></flag> </use> <upstream> <remote-id type="sourceforge">gretl</remote-id> </upstream> </pkgmetadata>
