Restoring rate

[JanJereczek]

Indicator summary

Linearizing a 1D nonlinear model, one obtains $\dot{x} = \lambda , x$, with $\lambda$ the restoring rate. It can be estimated in a way that is robust to changes in variance of the noise process leading to the fluctuations around the attractor. The restoring rate is a CSD indicator

Codebase

Not that I would know but should be easy to implement.
