By @seabbs in #742 and reviewed by @jamesmbaazam. +- Gaussian processes have been vectorised, leading to some speed gains 🚀 , and the `gp_opts()` function has gained three more options, "periodic", "ou", and "se", to specify periodic and linear kernels respectively. By @seabbs in #742 and reviewed by @jamesmbaazam. - Prior predictive checks have been used to update the following priors: the prior on the magnitude of the Gaussian process (from HalfNormal(0, 1) to HalfNormal(0, 0.1)), and the prior on the overdispersion (from 1 / HalfNormal(0, 1)^2 to 1 / HalfNormal(0, 0.25)). By @seabbs in #742 and reviewed by @jamesmbaazam. - The default stan control options have been updated from `list(adapt_delta = 0.95, max_treedepth = 15)` to `list(adapt_delta = 0.9, max_treedepth = 12)` due to improved performance and to reduce the runtime of the default parameterisations. By @seabbs in #742 and reviewed by @jamesmbaazam. - Initialisation has been simplified by sampling directly from the priors, where possible, rather than from a constrained space.
