RESI 1.5.1.9001

• Fixed resi_pe.lmerMod() handling for spline terms like ns(Days, 3) by reconstructing the auxiliary fixed-effects model data from the original model call and replacing deprecated lme4::nobars usage with reformulas::nobars.
• resi() now uses strict asymptotic CI dispatch for non-bootstrap methods (qf, cf, normal) with no automatic fallback to other methods.
• Updated print.resi() notes to report the actual CI method used (quadratic form, Cornish-Fisher, Gaussian normal, or bootstrap).
• Added regression tests for mixed-model spline handling, strict CI method behavior, CI note text, and improved determinism in randomized test fixtures.

RESI 1.5.1 (2026-08-21)

RESI 1.5.1

• Minor bug fixes with website rendering.

RESI 1.5.0

Bug Fixes

• Parametric estimator uses robust CIs (via type='HC3') -- this provides valid coverage for the expected value of the possibly biased estimator.
• Simulation calibration evaluation uses a true value that is consistent with the Monte Carlo simulation variance of R (RESI vector).

RESI 1.4.2

New Features

• Added analytic confidence intervals based on quadratic form, Cornish-Fisher, and Normal approximations. qf is now the default confidence interval method for lm and glm.
• Added support for robustbase models (lmrob and glmrob) via new resi_pe.lmrob, resi_pe.glmrob, resi.lmrob, and resi.glmrob methods. Both default to vcovfunc = stats::vcov, which uses the model's built-in robust sandwich variance. glmrob redirects sandwich::vcovHC to stats::vcov with a warning since vcovHC does not support glmrob (#12).

Bug Fixes

• Fixed error when passing a data argument containing NAs to resi() for GEE models (geeglm). Rows with NA in any model variable are now silently stripped before bootstrapping, matching the complete cases used to fit the model and preventing cluster-size mismatches during re-fitting (#51).
• Fixed misleading error in summary.resi() when a different alpha level is requested but confidence intervals cannot be recomputed. The message now clearly explains that either (a) bootstrapping is not supported for the model type, or (b) resi() was not run with store.boot = TRUE, and instructs the user to re-run resi() with the desired alpha directly (#53).
• Fixed resi() failing to compute the overall Wald test when the model response is a computed expression (e.g. log10(charges) or I(charges > 10000)). Previously the intercept-only reduced model could not be fitted inside forked parallel workers because update() tried to re-evaluate the expression in an environment where the underlying variable was not in scope. The fix constructs the reduced-model formula using the already-evaluated column name from model.frame(), avoiding any re-evaluation.
• Added an informative error when vcov.args = list(type = "const") is passed together with vcovfunc = sandwich::vcovHC. The message explains that type = "const" is the OLS sandwich (not robust) and directs users to use vcovfunc = stats::vcov for parametric variance estimation instead (#50).
• resi_pe now reports CS-RESI and L-RESI for lmer.
