(with a Web browser supporting image maps). The entire DEM set,
documentation, and a whole lot of other data is to be found here.
I just tried running all the demos through gnuplot beta 328, and
found that fit.dem and prob.dem don't work. Several of the fit statements
in fit.dem fail with a 'singular matrix' message (e.g. the fit on hemisphr.dat
and soundvel.dat) As for prob.dem, I eventually get the following message:
gnuplot> plot lognormal(x)
"prob.dem", line 438: y range is less than threshold : see `set zero`
Anybody else have these problems?
