truncated multivariate normal
...of X to be non-negative (except the first), and the first
dimension is strictly larger than zero.
Example:
X ~ NT_2(mu, Sigma),
where mu=c(0.5, 0.5) and Sigma=c([120, 191], [191,154]), with X_1>0
and X_2>=0
Could anybody help me?
Thanks in advanced.

1. Emma is performing an experiment that requires individual handling of some animals. The sizes of the animals are lognormally distributed: The natural logarithms of their sizes has a normal distribution with mean 3 and standard deviation 0.4. The time (in minutes) it takes to handle each animal is given by
10 + s · 1.5 + eε for animals with s ≤ 20 20 + s · 0.8 + eε for animals with s > 20
