A computer programmed to process a method for generating a sequence of random numbers of a 1/f noise has the following steps: 1). Determining a constant step &dgr; or instants of consideration t to t ; 2). Determining a desired spectral value &bgr;; 3). Determining the number n of the random numbers, to be generated, of a 1/f noise; 4). Determining an intensity constant const; 5). forming a covariance matrix of dimension (n&times;n); and 6). Forming the Cholesky decomposition of the covariance matrix , with the following steps being carried out for each sequence, to be generated, of random numbers of a 1/f noise: 1). Forming a vector of length n from random numbers normally distributed in &lsqb;0,1&rsqb;, and 2). Generating a vector of length n of the desired 1/f-distributed random numbers by multiplying the Cholesky-decomposition by the vector .

Method for generating a sequence of random numbers of A 1/f-noise

A method and system for screening out empirically data collected from various steps of a technical process operating based on a first set of parameters, by utilizing a screening algorithm to reduce the size of the empirical data set, thus improving the modeling and revising of the technical process. The algorithm utilizes various classes associated with the empirical values and within each class performs an assessment with respect to preselected threshold values. The algorithm also performs an assessment with respect to another preselected threshold value, for the class as a whole.
