摘要
从理论上阐明了逻辑曲线方法的概念,对其中参数的初始值估计和非线性优化计算方法及步骤进行了说明, 并从中选择最适合的方法,分别实现初始值估计和非线性优化.以此为基础,编制计算机程序,对深圳市全社会固 定资产投资数据进行分析,对数据的长度进行优选,最后做出预测,取得很好的效果.
The concept of logistic method was described in theory,and the paper also elucidated the method of getting initial value and the steps of optimizing,then the optimal algorithm was selected as the most suitable method.Based on these,a computer program was coded,and the total investment in fixed assets in Shenzhen city was forecasted through the analysis of investment data in Shenzhen and the selection of the length of the data was made.The final result is good enough.
