Feature request: variable-length argument lists to user-defined functions

4

#### Summary: Allow user-defined functions to have an argument list that ends with 0 or more arguments all of the same type. Call these _optional_ arguments. #### Description: Currently there...

gaussian_dlm_obs should allow nonnegative-definite matrices

2

#### Summary: Although it is not specified in the manual, gaussian_dlm_obs() gives an error if the C0 argument is nonnegative definite instead of positive definite. #### Description: The C0 argument...

gesd() does not implement the GESD test

2

The documentation for anomalize::gesd() states that it implements the GESD method, and references @raunakms's gesd() function. But whereas the GESD method and @raunakms's gesd() function compute the test statistic R_i...

pilot model misfiled

1

The pilot model is in example_models/ARM/Ch.14, but it's an example from Chapter 13.

Does not build

When I do "stack build", I get the following errors: directory must match >=1.2 && =1.1.0.2 &&

Time.Posix has insufficient range

4

Time.Posix is defined as type Posix = Posix Int where the integer field is in milliseconds since Jan. 1, 1970. However, the language documentation for Int states that "Int math...

Integer overflow in exponent

3

scientific 1 (maxBound::Int) * scientific 1 (maxBound::Int) evaluates to 1.0e-2.

Feature request: vectorized phi()

3

Stan has a vectorized $\Phi(x)$ (standard cumulative distribution function) but lacks a corresponding vectorized $\varphi(x)$ (standard normal density). You can't get this using `std_normal_lpdf()`, as it sums the log density...

"thin" argument affects diagnostics

3

**Describe the bug** If I use the same seed (to ensure reproducibility) and do two model$fit() runs with identical arguments except that one has thin=4, I get fewer divergent transitions,...

loo_moment_match fails for models that have a cholesky_factor_cov parameter.

5

**Describe the bug** Running loo(moment_match = TRUE) on a fit object that has a parameter of type cholesky_factor_cov[K] yields the error "cholesky_factor_free: y is not lower triangular; y[1,3]=x (found before...
