基于SPSS软件的黑河正义峡下泄水量预报分析(国外英文资料) 1.3 analysis method SPSS software is currently one of the worlds most popular statistical software, the basic functions including data management, statistical analysis, chart analysis and output management, can provide a new operating environment for medium and long term hydrological forecast platform and rich technical methods [5]. According to the requirements analysis, the author collected with software SPSS warbler falls gorge runoff in 1951-2000, resource or stepwise regression analysis, middle temperature and precipitation data [6], analysis steps are as follows. (1) open SPSS data file window, set up by the forecast object resource are (or) and three predictor observation variable sequence of SPSS data file and save. Three prediction is classification of the independent variable factor: warbler falls gorge runoff (m3), middle reaches area of the average annual rainfall (mm) and the annual average temperature (℃). In the data editing window, the multivariate linear regression analysis is carried out in the data editing window. Calculate the estimate of the forecast object according to analysis, regression, linear operation. The relative fitting error between the observed value of the discharge water and the estimate is generated according to the operation procedure of transformation to calculate variable. The SPSS software will automatically save these data and results in the data editing window. Then according to the graphics - old dialog - chart steps to generate resource calendar year or its estimate of the history of the fitted curve, SPSS software will automatically save the data in the data editor window and computing results, and the output in the output window eliminate factors and introducing the factor of statistical results, the related information, graphics, etc. (3) the regression effect is tested. SPSS software will automatically return to the effect of statistical tests, including the fit of the regression equatio
