技術說明

本發明係揭露一種相關性變數篩選系統及其篩選方法，其中，接收模組係接收複數個變數。第一篩選模組根據各該變數之相關係數值，依序篩選該相關係數值大於第一閾值之該複數個變數。第一運算模組根據第一篩選模組篩選過後之該複數個變數，分別運算對應各該變數之迴歸值及權重值。第二篩選模組根據該複數個權重值，依序篩選權重值小於第二閾值之該複數個變數。第二運算模組根據第二篩選模組篩選過後之該複數個變數，運算各該變數之分析值。第三篩選模組根據該複數個分析值，篩選大於一目標值之該複數個分析值。 The present invention discloses a relative variable selection system and the selection method thereof. In the present invention, the reception module receives a plurality of variables. Based on the correlation coefficient of variables, the first selection module selects variables which the correlation coefficient is larger than the first threshold value in order. Based on variables selected by the fist selection module, the first calculating module selects the regression value and the weighted value corresponding to those variables. Based on the weighted values, the second selection module selects variables which the weighted value is smaller than the second threshold value in order. Based on variables selected by the second selection module, the second calculating module calculates the analyzed values of those variables. Based on the analyzed values of variables, the third selection module selects analyzed values which is large than the targeted value.
