Inverse Gamma 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 an inverse gamma distribution when a lower bound is known beforehand.
