[Gretl-users] adjusting the precision of printouts

By default gretl prints regression coefficients and standard errors to 6 significant figures, and also by default the "summary" command prints a large array of descriptive statistics -- too large to fit all the stats for a given series on a single line -- using 5 significant figures. Nothing wrong with that, but for presentation purposes one sometimes wants to cut down on the number of figures (and/or statistics) shown. And it's a bit of a pain to have to round numerical output manually. There are now some mechanisms on place to make this easier. * For scripting use there's a new "set" variable, "gretl_digits". This controls the number of significant figures in regression output (including LaTeX and RTF), with a minimum of 3 and maximum of 6. It also governs the figures shown by "summary", though in this case we impose a maximum of 5. * I've revised the output shown by "summary" with the --simple option to include the median. With both mean and median shown one can infer skewness (roughly), making the simple printout more useable. In this case we now have a hard-wired precision of 4 significant digits (and each series fits on a single line). * In the GUI, the right-click popup menu in the model window now has a "Digits..." entry which lets you adjust the precision on the fly. This also governs the precision used by Copy (as plain text, RTF or LaTeX). * Also in the GUI, the "Summary statistics" menu item (when multiple series are selected) now offers the choice of "Main statistics" (corresponding to the --simple option) or "Full statistics".
