摘要: The present invention discloses a relative variable selection system and a selection method thereof. In the present invention, the receiving module receives a plurality of variables. Based on a correlation coefficient of variables, a first selection module sequentially selects variables with a correlation coefficient greater than a first threshold value. Based on the variables selected by the first selection module, a first calculating module selects a regression value and a weighted value corresponding to the foregoing variables. Based on the weighted values, a second selection module sequentially selects variables with a weighted value smaller than a second threshold value. Based on the variables selected by the second selection module, a second calculating module calculates analyzed values of the foregoing variables. Based on the analyzed values of the variables, a third selection module selects analyzed values which are greater than the target value.
