a sequence approximation function in which the sequence domain of the sequence approximation function that was created when the previous one sequential data was inputted is extended up to the newly inputted sequential data, and the specified function parameter that was created when the previous one sequential data was inputted is changed so as to approximate the values of the sequential data included in the extended sequence domain;

a collective domain, which is a domain of a specified range of the sequential data that are accumulated in the memory device in a continuous order, where the range of information that includes the order of that specified range of sequential data is divided into one or two or more, and a specified function parameter that approximates the values of the sequential data in that divided collective domain; and

Abstract
Each time sequential data is generated by a data generation source (001), the data is inputted into a sequential data memory unit (002) and accumulated in a memory device. Each time sequential data is inputted, a sequence summary unit (003) creates a sequence approximation function that approximates the inputted sequential data and previously inputted sequential data. A summary result memory unit (008) stores the sequence approximation functions that were created by the sequence summary unit (003). At specified timing, an accumulated data summary unit (005) creates, from a specified range of sequential data that was accumulated in the sequential data memory unit (002), a collective approximation function that approximates that sequential data with that range as the domain. A summary result evaluation unit (007) replaces the sequence approximation functions that were stored in the summary result memory unit (008) with the collective approximation function that has a domain that includes the range of the domains of the sequence approximation functions.
