Abstract (in Japanese) (See Japanese page) 
(in English) In statistical methods, such as statistical static timing analysis (S-STA), Gaussian mixture model (GMM) is a useful tool for representing a non-Gaussian distribution. In order to repeat summation, maximum, and/or minimum operations efficiently, the number of components should be restricted around two. Moreover, since the distribution is represented by a linear combination of some explanatory variables, we must compute the covariance between each explanatory variable and the distribution obtained by the operation, that is, we must compute the sensitivity of the distribution to each explanatory variable. In this paper, we propose a method to compute such sensitivities, and show performance evaluations of the method.
