Structural Reliability and Stability of Nonmetric Conjoint Analysis
研究了在严重结构扰动和刺激数量大幅变化时，非度量联合分析的结构可靠性与稳定性，发现该方法在评估个人偏好方面相当稳健。
Structural reliability and stability of nonmetric conjoint analysis are examined under conditions of severe structural perturbation and substantial variation in the number of stimulus profiles. The individual-level part worth functions are jackknifed. The jackknifed parameters, derived relative importance weights, and standard errors of estimated parameters are examined across the different treatment conditions. The results indicate that conjoint analysis is a fairly robust procedure for assessing an individual's preferences.
