Left censored responses in mixed effects models
Dear R Fellow-Travellers:
What is your recommended way of dealing with a left-censored response
(non-detects) in (linear Gaussian) mixed effects models?
Specifics: Response is a numeric positive measurement (of volume, actually);
but when it falls below some unknown and slightly random value (depending on
how the sample is prepared and measured), it cannot be measured and is
recorded as 0.

who broke keyboards again?
I have a client that has several dell machines, when he boots without
a keyboard he gets:
atkbdc0: <Keyboard controller (i8042)> at port 0x60,0x64 on isa0
but no:
atkbd0: <AT Keyboard> flags 0x1 irq 1 on atkbdc0
kbd0 at atkbd0
This used to work, then was broken by someone trying to "do the right
thing".
We need the keyboards to be hot swappable. I recommend that
