You're welcome. Here's a further suggestion for navigating the
gretl source, which I sometimes use myself if I forget where
* First, look up the gretl command code for the topic you're
interested in, using the command word. For least squares
regression the command word is "ols" and in
lib/src/gretl_commands.c a search for "ols" shows that the
corresponding numeric code is OLS.
* Now look up OLS in the central command execution code, in
lib/src/interact.c. This is a big "switch" and we find:
*models = lsq(cmd->list, pZ, pdinfo, cmd->ci, cmd->opt);
err = maybe_print_model(models, pdinfo, prn, cmd->opt);
This tells is that lsq() is the function that actually does the
work for OLS.
From this point on, the exact process depends on what code editor
you're using. I use emacs, and by typing "Alt" + "." over
"lsq" above, I'm taken to the point in the source where lsq() is
actually defined. Other C-source-aware editors presumably have
their own ways of doing this sort of thing.
