摘要： An information processing device can obtain an accurate result of regression analysis even if a mean and a variance of a response variable depends on an explanatory variable taking continuous variable. An information processing device calculates a mean of and a variance of a response variable for each range which is determined based on a partition candidate being information on partitioning a domain of an explanatory variable into a plurality of ranges based on observed data including information representing the explanatory variable and information representing the response variable being an observed value in terms of the explanatory variable and the mean and the variance are dependent on the explanatory variable. The information processing device selects a specific partition candidate among a plurality of the partition candidates by using an information criterion which is calculated based on the observed data and the calculated mean and variance of the response variable. The information processing device calculates a smooth function representing the variance of the response variable in the domain of the explanatory variable and a smooth function representing the mean of the response variable in the domain of the explanatory variable based on the mean and the variance calculated for each range determined based on the specific partition candidate.

摘要： A diagnostic device detects a fault and estimates its cause based on the degree of change of a plurality of attributes of data measured from an object being diagnosed. A diagnostic object change degree pattern generation unit 110 calculates the degree of change of each attribute of data, including a plurality of attributes of the object being diagnosed measured from the object being diagnosed to generate a diagnostic object change degree pattern which is a combination of values of the degree of change of the respective attributes. A criterion change degree pattern memory 150 holds in store a criterion change degree pattern, formed of a pattern of values of the degree of change of the attributes of data measured from the object being diagnosed, in association with event(s)-to-be-diagnosed on the fault sort basis or on the fault cause basis. A change degree pattern diagnosis means 120 effects pattern matching between the diagnostic object change degree pattern and the criterion change degree pattern in the criterion change degree pattern memory to diagnose the object being diagnosed.
