If model evaluates at initial conditions without autodiff but fails with autodiff then the error messages are not great

10

#### Summary: For instance, with an ODE model @jtimonen found output like this: ``` Rejecting initial value: Error evaluating the log probability at the initial value. Exception: ode_bdf_tol: Failed to...

Don't do inverse metric decomposition every draw

9

Fix for Issue #2881 . This involved switching to setter/getters for interfacing with dense_e_point so I made the change for diag_e_point as well. I also changed all the set_metric verbage...

Implement automatic selection of dense/diag metric at warmup

2

#### Summary: Implement the automatic selection between metric=dense_e and metric=diag_e as described in: https://arxiv.org/abs/1905.11916 #### Description It's not always obvious when the diagonal or dense metrics are the best. Or...

Doing the decomposition for every momentum draw is inefficient

12

#### Summary: For N parameters, there's an NxN Cholesky computed every time a new momentum is drawn. In reality we only need to recompute that when the metric changes. ####...

#### Summary: stan::io reimplements its own versions of ordered_free (https://github.com/stan-dev/stan/blob/develop/src/stan/io/writer.hpp#L211) and positive_ordered_free (https://github.com/stan-dev/stan/blob/develop/src/stan/io/writer.hpp#L237) instead of using the stuff in the math library I assigned it to you @syclik to evaluate...

#### Summary: This issue is to track what is yet to be done for varmat to go out in 2.27. Edit at will! This is a resurrected version of the...

#### Summary: With `STAN_THREADS=true` in `make/local`, if you: 1. Build a model 2. Modify the stan submodule source 3. Rebuild the model Nothing happens on step 3. If threading is...
