Embodiment
[0056] When a relevant data sequence is generated at a certain time, let the standard error σ x =100, standard error σ y =400, correlation coefficient ρ xy =0.3, and using the σ x , σ y and ρ xy , to construct a 2×2 covariance matrix P 1 and a 2×2 invertible matrix P, where,
[0057]
[0058] According to the invertible matrix P, for the covariance matrix P 1 Carry out contract transformation and calculate the covariance matrix P 1 The contract transformation matrix P 2 ,As follows,
[0059]
[0060] Transformation matrix P by the contract 2 , calculate the standard error σ of the n-dimensional data sequence X′ x′ and the standard error σ of the n-dimensional data sequence Y′ y′ . The contract transformation matrix P 2 The element at position (1, 1) of square root to calculate σ x′ =100, and the σ x′ As the standard error of the n-dimensional data sequence X'; the contract transformation matrix P 2 The element at position (2, 2) of square root to calc...
