Abstract: This paper discusses the sensitivity for linear restricted parameter estimations on the disturbance of design matrix, observation vector and restricted condition, and obtains appropriate sensitivity theorem for generalized ridge estimate and principal components estimate.

Key words: linear restriction, design matrix, disturbance, sensitivity, robustness, generalized ridge estimate, principal component estimate
