#### Summary: We would like to have asymmetric Laplace distribution to be implemented in stan. #### Description: As discussed in the [mailing list](https://groups.google.com/forum/#!msg/stan-users/DUv_uFFedCM/329AeWxYtBAJ), it is particularly of interest for Bayesian...
#### Summary: 2 questions: - should this still be included by file `stan/model/model_header.hpp` - should this be used by CmdStan to parse command line args, or is there a better...
#### Summary: Suggested changes 1. Move dim validation from model generated code to var_context (see example code below) 2. Optionally, move transforms into their own classes rather than triplets of...
#### Summary: It'd be nice to have a builder pattern for var contexts to make them easy to construct for testing. Something that could be used like this: ``` MatrixXd...
#### Summary: From Rob Goedman on stan-dev, there's an issue with two chains and thinning. #### Reproducible Steps: When running a mode My test model: simple.stan: ``` data {real sigma;}...
#### Summary: When we run the generated quantities facility we should allow for a threaded evaluation to speed things up. #### Description: As the draws from the posterior are independent...
#### 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: Looking over the Eigen docs I think we can support the following in the stan language ```stan data { int N; // rows int M; // cols int...
#### Summary: Two arguments to the service functions (all functions in `stan/services/...`) should be made constant: - [X] `io::var_context`: this should be easy as `var_context` has appropriate `const` declarations -...
I can get a segfault on Windows from cmdstan (or rstan) with the following model / data / syntax ``` ./weibull.exe variational data file=weibull.data.R random seed=1913258051 ``` [weibull.txt](https://github.com/stan-dev/stan/files/101339/weibull.txt) [weibull.data.txt](https://github.com/stan-dev/stan/files/101340/weibull.data.txt) This...
