1. A method for predicting a wind power density using a stepwise regression analysis technique, configured in a form of a program executed by an execution processing means including a computer, comprising:
a variable inputting step (S1) of inputting the wind power density, which is an output variable, and one or more input variables selected among ground roughnesses (r1 to r6), an elevation, a relative elevation difference, a terrain openness, a wide region terrain openness, aspects (a1 to a7), a slope, a relative slope, a mean elevation, a maximum elevation, a minimum elevation, a relative relief, a distance from a coast, and reinterpretation meteorology data; a stepwise regression analyzing step (S2) of receiving the output variable and the input variables input in the variable inputting step (S1) and performing a regression analysis method by a stepwise variable selection method; and a multiple regression equation estimating step (S3) of estimating a multiple regression equation having the highest Coefficient of determination (R2) value using regression coefficients calculated in the stepwise regression analyzing step (S2). |
