# BEAST 2 Help Me Choose Dirichlet offset

## Dirichlet offset

Offset of origin (defaults to 0), which shifts the distribution by a fixed amount, namely the offset. Setting the offset to x means lower bounds becomes x and the mean has x added to them. It does not affect the variance.

This can be useful for example to specify a node calibration with a gamma distribution when a lower bound is known beforehand.
