Stan development repository. The master branch contains the current release. The develop branch contains the latest stable development. See the Developer Process Wiki for details.
#### Summary: It is possible for ADVI to obtain a realization that is infinite, and if it writes that to a CSV file, reading the CSV file breaks. We should...
#### Summary: When running Stan programs with low sample sizes (under 300 samples,) Stan returns a (confusing/spurious?) warning regarding the warmup. #### Description: When running an analysis with a sample...
#### Summary: As pointed out by @bgoodri on stan-dev list, truncation syntax is generating ``` if (y < 1) lp_accum__.add(-std::numeric_limits::infinity()); else lp_accum__.add(-poisson_ccdf_log(1, rate)); ``` Instead it should be throwing `std::domain_error`...
#### Summary: @betanalpha fixed #1972. We should add a test so it doesn't recur. (Thanks, @YannickJadoul) #### Description: This model did not sample correctly in v2.10: ``` stan parameters {...
#### Summary: Extension of Bessel and modified Bessel functions to fractional order #### Description: Extension to fractional order would conform with their implementation in base R. #### Current Version: v2.9.0
#### Summary: Defining a size 0 correlation matrix leads to std::bad_alloc in rstan. This is related to #2588, where it is suggested that corr_matrix and related types should be able...
#### Summary: it's possible to create ragged arrays using array expressions and pass them in to user-defined functions. this shouldn't be allowed until we have proper support for ragged arrays....
#### Summary: For [reader.hpp](https://github.com/stan-dev/stan/blob/develop/src/stan/io/reader.hpp) we need methods for `static_matrix(i, j)` and `static_vector(i)` to read in a static matrix. One small issue atm is that when we call [`log_prob_grad`](https://github.com/stan-dev/stan/blob/develop/src/stan/model/log_prob_grad.hpp#L29) or [`log_prob_propto`](https://github.com/stan-dev/stan/blob/develop/src/stan/model/log_prob_propto.hpp#L38)...
#### Summary: Once [#2024](https://github.com/stan-dev/math/pull/2024) goes into math we'll be able to have cheap views into `var_value` types. One Q is whether we should spend extra time when someone writes something...
We've recently discussed how CmdStan does not have a way to provide users access to the initial values it used: * https://discourse.mc-stan.org/t/does-the-init-argument-work-with-cmdstanr/17255/19 * https://github.com/stan-dev/cmdstan/issues/918 It sounds like this is actually...
