The result of a measurement may not depend significantly on the actual number of repeat measurements, which implies that outliers should not be allowed to play a critical role with regard to the positioning of estimators – though, in individual cases, it might well be recommendable to rely on sophisticated decision criteria. On the other hand, judging from an experimental point of view, it could be more advantageous identifying the causes of outliers. When we assume that the consecutive numbers x1 , x2 , .

The consecutive pairs (Xl , Yl ); l = 1, . . , n are assumed to be independent, however there may be a correlation between Xl and Yl . In particular, each Xl is independent of any other Yl ; l=l. We now consider the expected value of the empirical covariance sxy = 1 n n (xl − µx )(yl − µy ) . 2 Variances and Covariances 57 Letting Sxy denote the associated random variable, we look after the expectation E{Sxy } = n 1 E n (Xl − µx )(Yl − µy ) . l=1 Obviously E{Sxy } = 1 n n 1 nσxy = σxy . 17) More effort is needed to cover ∞ ∞ ¯ − µx )(Y¯ − µy ) = E (X (¯ x − µx )(¯ y − µy ) pX¯ Y¯ (¯ x, y¯) d¯ x d¯ y −∞ −∞ = σx¯y¯ .

55) Obviously, the quantity Sz2 implies the empirical covariances between the m variables Xi ; i = 1, . . , m be they dependent or not. We have (l) (l) z (l) = b1 x1 + b2 x2 + · · · + bm x(l) m , z¯ = b1 x ¯1 + b2 x ¯2 + · · · + bm x ¯m so that s2z = 1 n−1 n (l) (l) b1 (x1 − x ¯1 ) + b2 (x2 − x ¯2 ) + · · · + bm (x(l) ¯m ) m −x 2 l=1 = bTs b . 56) The matrix notation on the right hand side refers to the empirical variance– covariance matrix s of the input data, ⎞ ⎛ s11 s12 . . s1m n ⎜ s s ...
