refactor(glm): preserve binomial normalization without ifelse#87seonghobae wants to merge 6 commits into
Conversation
Replaced two `ifelse` calls with direct division and vectorized conditional reassignment in the `binomial` switch case inside `llcont.glm`. This avoids evaluating both true and false branches entirely before subsetting.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The binomial likelihood optimization preserves zero-count and zero-weight behavior, but missing response totals are not covered by the new contract tests. This leaves a bounded risk of changed likelihood contributions for models containing missing binomial counts. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Around line 4-5: Extend the tests around the existing successes and failures
vectors to include a response whose rowSums(y) contains NA, then assert the
expected contribution output after the !is.na(n) correction and subsequent m
branch. If NA totals are intentionally unsupported, explicitly remove this case
from both the test and the target behavior instead.

NA 총합 경로에 대한 회귀 테스트를 추가하십시오.
현재 테스트는 NA가 없는 matrix response만 사용합니다. 따라서 rowSums(y)가 NA를 반환하는 경우의 !is.na(n) 보정과 후속 m 분기를 실행하지 않습니다. NA 총합을 포함한 response를 추가하고, contribution의 기대 결과를 명시하십시오. 해당 입력이 지원 범위가 아니면 테스트와 목표에서 제외한다고 명시하십시오.

a3b350d95f3215c6d0b82257ef6b756d3bc339bfis Draft and mechanically ahead ofmaster@807f80c6a0b1f1d362eb9f398264de298bdd6b1cwith no base lag. The effective diff is now intentionally limited toR/llcont.Rplustests/testthat/test_llcont_binomial_ifelse_contract.R.The product change replaces two
ifelse()expressions in the binomialllcont.glm()path with direct division followed by indexed correction. This is treated as a semantics-preserving refactor until measured otherwise; the previous 30–40% speedup claim had no committed reproducible benchmark and is not promotion evidence.Repair performed
Unrelated changes to
.github/workflows/R-CMD-check.yamland the generated repository-wide.jules/bolt.mdrule were restored to the protected-base blobs. This PR therefore does not change CI triggering policy or establish a global mathematical-shortcut rule from one local optimization.A focused regression now covers two boundary conditions the existing normal-binomial tests did not isolate:
NaNcase contributions and the contribution sum must remain equal tologLik();logLik().Existing ordinary binary and grouped-binomial parity tests remain in place.
Promotion boundary
Do not describe this as a 30–40% improvement, GC reduction, or buyer-visible latency gain without a reproducible benchmark on supported R/runtime versions and representative binomial workloads. If performance promotion is pursued, record workload size/distribution, runtime/platform, warm-up and iteration policy, baseline/current wall time and allocation evidence, and semantic parity.
Before Ready/merge, require fresh exact-head R-CMD-check and repository-required security/quality checks, current review/thread state, and no regression in the zero-total/zero-weight contracts. Predecessor GREEN, self-approval, gate weakening, no-op retriggers, or force rewrites are not evidence.
