摘要: Tanaka(1988) derived two influence functions related to an ordinary eigenvalue problem (A–λs I)vs = 0 of a real symmetric matrix A and used them for sensitivity analysis in principal component analysis. One these was develop factor (see e.g. Tanaka Odaka, 1988a). The present paper derives some additional also several generalized (A–θs A)us 0, where B are positive definite matrices, respectively. These applicable not only the case eigenvalues interest all simple but there multiple among those interest.
