Dear Halton A.Peters:
I am a graduate student in South China Botanical Garden.I am reading your paper entitled "Neighbour-regulated mortality; the influence of positive and negative density dependence of tree populations in species-rich tropical forests"published on <Ecology letters> in 2003.
I have some questions about the Analitical methods part. The questions are listed below.
1.is the dependent variable "the survival of individual trees" ?
2.are all the variable including dependent and independent variables Box-Cox transformed?
3.you wrote that:"Transformations were performed using the Box-Cox prodecure to ensure a priori that the assumption of the regression were not violated" . As I know ,the assumptions of multiple regression are mostly about the residuals. It is only after regression is done that one can test the assumptions of multiple regression. And box-cox transformation cannot ensure that the distribution and variance of the residuals meet the needs of multiple regression.
I am looking forword to your reply . Thank you very much.

貌似问题不少。总体上,格式最好采用不缩进,没段空一行的方式,看起来会比较舒服。
Dear Halton A.Peters:/**//**//**//**/
/*说dear,总得给人一个title吧,加上Mr.或者Pro.*/
I am a graduate student in South China Botanical Garden./*说了身份,最好写上自己的名字,虽然对方很难记住,都陌生人。*/
I am reading your paper entitled "Neighbour-regulated mortality; the influence of positive and negative density dependence of tree populations in species-rich tropical forests"published on <Ecology letters> in 2003.
/*
这一段问题比较多。
首先,“ mortality; the influence”这之间的分号就不可能是对的,冒号吗?
entitled可以删掉;
文章标题去掉双引号,改用斜体;
对杂志<Ecology letters>,去掉单书名号,改用斜体;
在文章标题列完之后,加上逗号,说which appeared in××会不会好些?
对期数之类的信息写详细些,人家当然知道,写出来显得你比较专业。

是冒号,
我喜欢用entitled
一般情况下,在不影响理解的前提下,我不太想花时间注意标点符号

我提问自然是有原因的,
在不原文没有明确表明的前提下,我不觉得我的问题seem to be stupid

看了这个帖子,说句公道话。jthu不辞劳苦的写了那么多comments, 应该是没有功劳也有苦劳的。楼主没必要那么义愤填膺。

我只是不想离题,因为我的目的并不是讨论英语!
