Implementation Reference

• src/tools/index.ts:1747-1758 (handler)

  The handler function that implements the logic for the marginal_effects_guide tool, providing explanations of marginal effect types and code snippets for R and Stata.

  function handleMarginalEffectsGuide(args: Record<string, unknown>) {
    return {
      model_type: args.model_type,
      effect_types: {
        ame: "Average Marginal Effect - 평균적 한계효과",
        mem: "Marginal Effect at Mean - 평균값에서 한계효과",
        mer: "Marginal Effect at Representative values"
      },
      r_code: "margins::margins(model)",
      stata_code: "margins, dydx(*)"
    };
  }

• src/tools/index.ts:497-505 (schema)

  Input schema defining parameters for the marginal_effects_guide tool: model_type (required), effect_type, and interaction.

  inputSchema: {
    type: "object",
    properties: {
      model_type: { type: "string", enum: ["logit", "probit", "poisson", "tobit"], description: "모형" },
      effect_type: { type: "string", enum: ["ame", "mem", "mer"], description: "한계효과 유형" },
      interaction: { type: "boolean", description: "상호작용항 포함" },
    },
    required: ["model_type"],
  },

• src/tools/index.ts:494-506 (registration)

  Tool registration object in the tools array, including name, description, and inputSchema.

  {
    name: "marginal_effects_guide",
    description: "한계효과 계산 및 해석 가이드",
    inputSchema: {
      type: "object",
      properties: {
        model_type: { type: "string", enum: ["logit", "probit", "poisson", "tobit"], description: "모형" },
        effect_type: { type: "string", enum: ["ame", "mem", "mer"], description: "한계효과 유형" },
        interaction: { type: "boolean", description: "상호작용항 포함" },
      },
      required: ["model_type"],
    },
  },

• src/tools/index.ts:854-855 (registration)

  Switch case in handleToolCall that routes calls to the marginal_effects_guide handler.

  case "marginal_effects_guide":
    return handleMarginalEffectsGuide(args);
