Origin
[edit]Created by me using this bit of gnuplot
This plot was created with Gnuplot by n.
and dema.data
created by this bit of perl
$N = 10;
$f = 1 - 2/($N+1);
$total = 0;
foreach $i (0..39) {
$value =
2 * 100.0 * (1 - $f) * ($f ** $i)
- 100.0 * (1 - $f) * (1 - $f) * ($i + 1) * ($f ** $i);
print "$i $value\n";
$total += $value;
}
print "# total $total (should approach 100)\n";
