A compiler for Bayesian time series models.
For the process qp(P, ell, n, rho, sigma), ell currently must be a numeric literal or a variable whose definition is a numeric literal. Extend things so that ell need...
Should allow exponential_mt(mean, ub) to have mean >= 0.5 * ub. Likewise should allow exponential_rt(theta, ub) to have theta
The current ar1() function is flexible but difficult to use. Should create a new version for the stationary ar1(). One of the parameters should be the stationary variance; the other...
There are instances where Chronikis-generated Stan code has subexpressions being computed in the model section that could be computed in the transformed data section. This should be fixed so that...
### Expected Behaviour qp() currently only supports constant values for certain arguments, and should produce an error message stating this when a call to qp() has a non-constant expression for...
### Expected Behaviour The expression qp(pyear, ell_py, 10, rho_py, sigma_py) should properly expand if `pyear` and `ell_py` were previously defined as literals or (more generally) constant expressions. ### Actual Behaviour...
### Expected Behaviour It should be OK to have the following in a Chronikis program: qp(24.0 * 7.0, 0.5, 10, rho_w, sigmap_w) ### Actual Behaviour I get the following error:...
