Implementation Reference
- src/tools/index.ts:1711-1732 (handler)Handler function that executes the tool logic: interprets the coefficient based on model type (OLS/linear or logit/logistic), computes odds ratio if applicable, and returns a structured interpretation with caution note.
function handleInterpretCoefficient(args: Record<string, unknown>) { const modelType = args.model_type as string; const coefficient = args.coefficient as number; const variableType = args.variable_type as string; let interpretation = ""; if (modelType === "ols" || modelType === "linear") { interpretation = `X가 1단위 증가하면 Y가 ${coefficient.toFixed(3)} 단위 변화 (다른 변수 통제)`; } else if (modelType === "logit" || modelType === "logistic") { const or = Math.exp(coefficient); interpretation = `Odds Ratio = ${or.toFixed(3)}. X가 1단위 증가하면 odds가 ${((or - 1) * 100).toFixed(1)}% 변화`; } return { model_type: modelType, coefficient, variable_type: variableType, interpretation, caution: "인과적 해석은 연구설계에 따라 결정" }; } - src/tools/index.ts:466-479 (schema)Input schema definition for the interpret_coefficient tool, specifying parameters like model_type, coefficient (required), se, variable_type, and transformation.
