Calculates the effective sampling rate (esr) for each parameter.

esr_pars(x, ...)

Arguments

x

An object.

...

Other arguments passed to methods.

Value

A uniquely named numeric vector of values between 0 and 1 indicating the esr value for each parameter.

Details

By default $$\frac{1}{1 + 2 \sum_{k = 1}^\infty\rho_k(\theta)}$$ from Brooks et al. (2011) where the infinite sum is truncated at lag \(k\) when \(\rho_{k+1}(\theta) < 0\).
