谢谢您在S-Plus/R中的指导,我想把我的问题再具体的描述一下,我的论文做的是:应用遥感数据及少量的地面调查数据对森林的蓄积量进行预测(预测变量为遥感影像的灰度值和地物类型,目标变量为森林蓄积量;它们都是以二维表的形式组织的),现在我基本上已经完成了应用样本数据拟合好了模型,并在知道了如何应用拟合好的对未知蓄积量的数据(也是二维表的形式)进行预测,现在剩下的问题是:如何把预测完了数据(二维表)转换成图像? |

现在又有一个问题了,是这样的:我要用遥感信息(连续型)和地物类(字符型)型建立一个关于预测森林蓄积量(需要是连续型)的神经网络模型。可是在建立神经网络模型时,设置蓄积量为连续型变量,系统提示出错,说什么该变量不能为该类型!但在我的预测中,目标变量需要是连续型的(因为各块林地上的森林蓄积量是连续变化),而且当我把它改成是离散型(只是试验,实践是不应该这样的),预测的精度的各项结果均为0,非常的迷惑!! |

不过有一点就是我的模型不是太稳定,就是说的参数的设置的不同,对起进行评价时,Relative S.. erorr相差很大 |

谢老师您好~~我最近再用Rmarkdown整理一份医学统计学的学习笔记,您可以在https://bookdown.org/wxhyihuan/Notebook-of-medical-statistics-1605856202966/ 这里了解,目前还在更新当中,谢谢您的各种资料,帮助很大! |

我刚发现用我们的博客在国内都访问不了了,这是官方的解决办法: https://www.vercel-status.com/incidents/r758bhbklgfd 把 ANAME 从 76.76.21.21 改为 76.223.126.88 实际上这两个记录改不了,我是直接添加新记录的。弄完之后可以访问了,过来告诉你一声,免得你再花时间放狗搜索。有点想分享到统计之都的,但又不知道谈论这些合不合适。 |

益辉大大,最近我在使用您开发的bookdown写书,我发现PDF输出里的参考文献格式一直不太对,找了一圈都没找着怎么处理。今天新开了个issue: 有空帮忙看看,谢谢啦! |

您好,一直关注您的博客。最近我也从wordpress迁移到Jekyll,很多事情还没弄好,故私自借用了您的模板,不知您是否介意?博客还没做好,故链接就没放上。我会边学边改,创出我的模板风格。 |
