Implementation Reference
- src/tools/index.ts:1073-1104 (handler)The main handler function `handleCompareMethods` that implements the tool logic. It compares pairs of statistical methods (e.g., FE vs RE, DID vs SCM) using predefined comparison data and falls back to suggesting another tool if no predefined comparison exists.
function handleCompareMethods(args: Record<string, unknown>) { const methods = args.methods as string[]; const comparison: Record<string, any> = { fe_vs_re: { methods: ["Fixed Effects", "Random Effects"], key_difference: "FE는 개체 고정효과와 X 상관 허용, RE는 비상관 가정", decision: "Hausman test: H₀ 기각 → FE, H₀ 수용 → RE (효율성)", tradeoff: "FE: 일관성 | RE: 효율성 (시간불변 변수 추정 가능)" }, did_vs_scm: { methods: ["DID", "Synthetic Control"], key_difference: "DID는 다수 처치/통제, SCM은 단일 처치 단위에 적합", decision: "처치 단위 수: 1 → SCM, 다수 → DID", tradeoff: "DID: 통계 검정 용이 | SCM: 평행추세 가정 완화" }, psm_vs_iv: { methods: ["PSM", "IV/2SLS"], key_difference: "PSM은 관찰변수 통제, IV는 비관찰 내생성 해결", decision: "Selection on observables → PSM, Selection on unobservables → IV", tradeoff: "PSM: 도구변수 불필요 | IV: 비관찰 교란 통제" } }; const methodKey = methods.sort().join("_vs_"); const result = comparison[methodKey] || { methods, message: "상세 비교를 위해 search_stats_knowledge 도구 사용을 권장합니다." }; return result; } - src/tools/index.ts:73-92 (registration)Registration of the 'compare_methods' tool in the exported `tools` array, including its name, description, and inputSchema definition.
