The Landsat TM sensor tor rhrrmal infrared measurement has lower spatial resoltion than that of other six measurements. Nishii et al (1996) proposed a procedure to corrct the measurement by a linear combination of remaining high-resolution measurements. To find an efficient combinationof measurements, the averaged information) criteria based on AIC are purposed. Then the efficiency of the procedure is assessed through SSE by using actual TM data. 相似文献

In the class of all densities with constraints E bi(X) = c,(i = 1,....,q), it is well known that the entropy is maximized by the density belonging to the exponential family specified by bi(x), i = 1,....,q. Our aim in this note is to generalize theresult by using expected log likelihood. 相似文献

We consider the identity associated with the expected values of the matrix-valued quadratic forms of two random matrices. As a special case the identity yields the matrix-valued inequality of the Schwarz type. The most important application is for Loewner's theory in the context of the operator-monotone function, and the inequalities based on the concavityconvexity of the matrix-valued functions are derived. 相似文献
