来自主题: Statistics版 - Import XLSX 格式的EXCEL文件问题
Thanks for the reply.
Is there anyway that I can change XLSX to CSV in the program? I think I
would have to import the XLSX file first, then I can change it to CSV.
LIBNAME won't work for XLSX, as far as the info I can google.

昨天刚写了几段code,不过是对csv的,请你改一下用在Excel文件上吧。中间有些地方
可能不太完善(比如文件名不能有空格等),欢迎改进及简化。

stata import data from csv file之后, 本来csv里面variable name当中的空格就被
自动去掉了,比如date of birth变成dateofbirth
但是我看到前面的人留下的data,空格变成了下划线date of birth=> date_of_birth
我需要apending data,所以名字得保持一致
谁能告诉我怎么样才能变成下划线啊
many many thanks

来自主题: Statistics版 - regression estimator in importance sampling
有个问题请教。
在做importance sampling时,对于f=N(0,1)(原始分布)和N(Za,1)(distorted分布
),Za=2.326,求解P(X<= Za)。
我发现对于mean值,相对于simple sampling,Regression Estimator收敛性很好,但
是其平均值确比较偏离正确值,似乎是biased estimator。但文献中都说是无偏估计。

可以参看Page25,实际页数为37上的table。

The maximum length of any character value in SAS is 32,767 bytes.
You should add a statement to PROC IMPORT when reading CSV, TXT or EXCEL.

来自主题: PhotoProcessing版 - LR4如何import多张照片
从SD卡里import照片到电脑里,因为不想全部导入,怎么样才能check多照照片。我看
可以选择全部check和uncheck,但是只check指定的几张确不行,shift键按着只能选定
某张照片,但是无法打勾。到底有什么方法实现吗?

来自主题: DataSciences版 - random forest/xgbclassifier的feature importance
feature importance就是tree里面的entropy
你去掉了一个,排第二的只不过取而代之而已。

来自主题: DataSciences版 - random forest/xgbclassifier的feature importance
大概300个feature
恩。你说的很对,有一些跟feature-1相关的其他feature就“顶上来”替代了
不过,既然这个feature-1占了0.3这么大比例的importance,为何去掉后,百分比之降
低了6%?

What features are important for a particular use are a very personal thing.
And.. The features needed for hiking are a bit more extensive (and a bit d
ifferent) from those needed for automobile navigation use. Below are my "es
sential hiking feature list" of GPS receiver features.
(I omitted features that are present in ALL receivers.)
