Correspondence analysis for symbolic contingency tables based on interval algebra

AbstractIn this paper, we propose interval algebraic correspondence analysis (IACA), a new correspondence analysis method for interval contingency tables based on interval algebra. The interval contingency table, which is made by counting up the observations measured by two multi-valued variables, is an extension of the classical contingency table. Correspondence analysis for the interval contingency table has been proposed by Rodŕiguez[8] (SymCA); this analysis is based on the centers method in principal component analysis for the interval variables (Cazes, et al.,[2]). However, his method has the disadvantage that when computing statistical indices, the internal variation of intervals is lost. To overcome this problem, we propose a new correspondence analysis through which the internal variation of the interval is retained. A numerical example using IACA is discussed and the usefulness is shown

明治維新後の皇室における仏教信仰

I argue here that Buddhist faith endured in the imperial court, notably with the empress and members of the imperial family, even after the court relocated to Tokyo and after the new government had issued its shinbutsu bunri edicts, which aimed to separate kami practice from Buddhist practice. After 1877, all members of the imperial family were required to perform Shinto-style rites for their ancestors, at least in appearance. However, Buddhist faith was allowed within the private sphere. After its restoration in 1883, the Sen\u27nyuji temple was positioned anew as the ancestral temple for all the emperors who had lived in the erstwhile capital of Heian. Moreover, the funerals for Dowager empress Eisho in 1897, and for Prince Akira in 1898, were both performed accrding to esoteric Buddhist practice. It is clear, too, that in the new imperial palace in Tokyo, the emperess\u27s personal belief in the nenbutsu continued unabated
