 AdvancedMH.jl also offers an implementation of [MALA](https://en.wikipedia.org/wiki/Metropolis-adjusted_Langevin_algorithm) if the `ForwardDiff` and `DiffResults` packages are available. 
 
 A `MALA` sampler can be constructed by `MALA(proposal)` where `proposal` is a function that
-takes the gradient computed at the current sample. It is required to specify an initial sample `init_params` when calling `sample`.
