Hi. Does anyone recognise this distribution? I'm guessing that a
truncated lognormal distribution would probably fit. But it will take
me some time to work out how to fit the distribution to the data, and
if there are any recommendations of other distributions to look at
first, it would be greatly appreciated.

I sent a reply on this but it hasn't shown up -- possibly because I tried to
include an attachment. Maybe the ng doesn't accept attachments. Or I just
screwed it up. I'll try again, without attachment:
It's probably uniform, on (0,100). I plotted a histogram and an empirical
cdf and fit a uniform to them -- almost perfect fits. If you would like to
see these plots email me and I'll send them to you directly.
