# Slot: correlated_over 


_Which axis `covariance` indexes — `node` (equivalently `region`) for spatially correlated drive, or `state` for correlation between the noise on different state variables. Required whenever `covariance` is set: a covariance without a named axis does not identify a process. A multi-mode model carries its modes inside the state axis, so a modal covariance is declared over `state`._
