exdqlm 0.4.0

New

• Consolidated CRAN release (updating CRAN 0.3.0) that bundles the internal 0.4.0/0.5.0/0.6.0 feature line in one submission.
• exdqlmLDVB: Laplace-Delta variational Bayes routine for dynamic quantile state-space fitting under the extended asymmetric Laplace error distribution.
• Reduced-model controls for dynamic routines (exdqlmISVB(), exdqlmLDVB(), exdqlmMCMC()) through dqlm.ind = TRUE, fixing gamma = 0 for AL/DQLM inference when desired.
• Added synthesis helper quantileSynthesis() for combining posterior quantile-draw objects.
• Added dynamic regression-block construction with regMod() and static exAL inference routines for VB/LDVB and MCMC workflows.
• Added static reduced AL support (dqlm.ind = TRUE) in exalStaticLDVB() and exalStaticMCMC().
• Added static coefficient prior options for ridge and regularized horseshoe (beta_prior = "ridge" / "rhs") in both static LDVB and static MCMC.
• Added additive static rhs_ns prior support for both static LDVB and static MCMC (beta_prior = "rhs_ns"), including slab-control aliases (a_zeta, b_zeta, zeta2_fixed) while preserving existing rhs and ridge behavior.
• Added exdqlmTransferLDVB() for post-fit transformed summaries analogous to the ISVB path.
• Added exdqlmTransferMCMC() for fixed-lam transfer-function exDQLM fitting under the dynamic MCMC workflow.
• Documentation updates for new APIs: explicit argument contracts (types/dims), return-value structure, and CRAN-safe examples aligned with existing package style.
• Standardized VB diagnostics traces across VB fits via fit$diagnostics$vb_trace, exposing iteration-wise ELBO, sigma, gamma, and convergence deltas in a plot-ready table while preserving the existing engine-specific diagnostics.
• Standardized the main user-facing naming scheme around exalStatic..., exdqlmTransfer..., and quantileSynthesis(), while retaining documented legacy ISVB entry points where needed for backward-compatible workflows.
• Added climateIndices, a documented monthly NOI/AMO climate-index data frame used for reproducible external-regressor examples.

Fixes and clarifications

• Normalized the shared dynamic exDQLM VB policy around LDVB: exdqlmLDVB() and exdqlmTransferLDVB() are now the main VB entry points, while exdqlmISVB() and exdqlmTransferISVB() are documented as legacy compatibility paths.
• Added al.ind as a static-model convenience alias for dqlm.ind in exalStaticLDVB() and exalStaticMCMC(), with conflict checks when both flags are provided.
• Changed fix.sigma defaults from TRUE to FALSE for the shared dynamic exDQLM VB entry points and the reduced dynamic DQLM CAVI helper, while preserving explicit fixed-sigma workflows when users request them.
• Fixed R-path FFBS backward transition indexing to use G_{t+1} for parity with the C++ bridge and theory derivations.
• Fixed static MCMC psi = 0 boundary behavior in exAL sigma updates to avoid unstable scale draws in reduced/near-reduced settings.
• Aligned static LDVB (sigma, gamma) transformed objective/entropy handling with the Jacobian contract used in the static theory reference.
• Corrected the positive-truncated-normal entropy sign used in exAL LDVB monitored ELBO diagnostics and centralized the shared entropy calculation.
• Clarified that C++ elbo.part in kalman.cpp is an internal diagnostic; package-level ELBO reporting remains R-level contract output.
• Added dedicated static-fit object generics for exalStaticMCMC and exalStaticLDVB and aligned post-fit compatibility for exdqlm classes.
• Replaced deprecated arma::is_finite(...) usage in FFBS C++ with std::isfinite(...) to eliminate compiler deprecation warnings.
• Optional C++ builder acceleration remains opt-in (exdqlm.use_cpp_builders default FALSE); no backend default flip in this release.
• Optional C++ post-predictive sampler remains opt-in (exdqlm.use_cpp_postpred default FALSE).
• Transfer-function wrappers now share the same augmentation helper and accept either one or two discount factors through tf.df.
• Shared entry points now apply a conservative automatic warmup baseline for the most failure-prone common blocks: RHS-family tau scheduling remains on by default, while exAL VB/MCMC entry points apply a light (sigma, gamma) warmup unless users explicitly override it through vb_control or mcmc_control.
• Streamlined default LDVB/MCMC console progress lines to prioritize run phase, iteration, keep counters, acceptance summaries, and runtime while leaving full sigma/gamma histories in diagnostics objects and callbacks.
• Clarified the BTflow dataset provenance as observed monthly USGS streamflow and removed the unused BTprec dataset from the package data API.
• Slimmed the shipped climate-index data API to the two manuscript predictors used in the Big Trees example.
