<p>该问题的提法有问题,这是一个不可以研究的问题,首先,表1中的价格只给出了三个月的数据,又无明显的规律,要你预测未来价格的变化,从预测方法来讲没有一个方法可以实现,用任何方法所到的结果都是不可信,说白了都是胡扯!所以说这个问题的提法是不合适的!如果增加一些数据,而且有一定的规律,才可以研究!</p>

&nbsp;&nbsp;&nbsp; 几天前的一门管理课程上,老师让我们用不到五年的时间序列预测下一年的数据。对于类似的很多问题,在数学上是很难找到一种完全可信的方法的。但在实际工作中,这种信息不足的情况是很常见的。我觉得,在这种情况下,应该做的是利用现有数据得到尽可能可靠的结论,而不是等待更多的信息。<br/>&nbsp;&nbsp;&nbsp; 对问题本身没做太深入的研究,只是一点个人看法,请韩老师和各位网友指正。

<p>不管是谁出的题目,就这个问题而言,对未来作预测是没有任何意义的!如果作为数学方法的练习,不考虑具体的实际问题,那用什么方法都无所谓了,反正其结果都不能说明问题!</p><p>&nbsp;&nbsp;&nbsp; 对于小样本的数据做预测,最简单的方法是直接拟合;最好的方法是灰预测,但外推时间都不能太长,而且必须要求样本数学要有明显的变化趋势,否则是不可信的。</p><p>&nbsp;&nbsp;&nbsp; 对于大样本的数据预测,常用的方法是回归拟合、时间序列,神经网络等主,如果是带有随机性和周期性的数据样本,最好的方法是时间序列。某些简的情况也可以做多项式拟合,但次数不能太高!</p><p>&nbsp;&nbsp;&nbsp; 2003年SARS问题的旅游数据的预测最好的方法是灰预测和时间序列;</p><p>&nbsp;&nbsp;&nbsp; 2004年长江水质问题的预测最好的方法是灰预测和回归拟合,多项式拟合不超过三次也可以;</p><p>&nbsp;&nbsp;&nbsp; 2006年艾兹病问题大家想想该用什么方法?????????</p>[em01][em01][em01][em01][em01][em01][em01]

有一天,乔治在删除垃圾电子邮件的时候,看到这样一个标题:令人吃惊的足 总杯比赛预报。他好奇地点开了它,里边写着:亲爱的球迷,我们知道你是个怀疑论者,凡事不会轻易相信,可我们确 实已经设计出了绝对准确的预报足球比赛结果的奇妙方法。今天下午,英国足总杯将 进 行第三轮比赛,对垒的是考文垂队和谢菲尔德联队,我们预报考文垂队将会取得胜 利。乔治看过后,轻蔑地一笑,没有当回事。晚上,他收看电视里的比赛结 果,考文垂队果然势如破竹地赢了。
