DEFAULT DATA ESTIMATING DEVICE AND METHOD AND DEFAULT DATA ESTIMATING PROGRAM AND RECORDING MEDIUM WITH ITS PROGRAM RECORDED THEREON

摘要

PROBLEM TO BE SOLVED: To provide a default data estimating device, a default data estimating method, a default data estimating program and a recording medium for recording its program thereon capable of highly precisely estimating default data by simple processing. SOLUTION: A CPU 3 acquires a development amount matrix where the logarithmic values of the development amounts of gene development profile data are arranged, and estimates the parameter of a stochastic main component analytic model where each gene vector is interrupted as an independent sample in the development amount matrix by repeating Bayes estimation like a variational method under ARD preliminary probability distribution to estimate the missing value of the gene development profile data.
