首先,我们在数据框中添加一个布尔列,指示每个日期是在旺季还是淡季: is_nfl_season <- function(ds) { dates <- as.Date(ds) # 每一个元素类似于"2016-01-15" month <- as.numeric(format(dates, '%m')) # format(dates, '%m')返回字符类型的月份 # as.numeric转换成数字 return(month > 8 | m...

R自动把p(概率)作为排序靠后的类别的概率,于是运行代码levels(w2$V7)时,得到“AB”“NO”,p指的是NO的概率(R按照字典排序) 按照总误判率来寻找p值得阈值的函数如下: BI=function(D,w,ff,fm="binomial"){ a=glm(ff,w,family=fm) z=predict(a,w,type="response") ee=NULL for(p in seq(.1,.9,...
R语言内置函数(Built-in Functions) R中几乎所有的事情都是通过函数完成的。 下表提供了其它常用的统计函数。 R语言中每个数值运算函数都有na.rm选项,以便在计算前删除缺失值。否则,缺少值的存在将导致结果也是缺失值。统计函数的运算的对象可以是向量也可以是dataframe Function Description mean(x, trim=0, na.rm...

In addition, foot shocks stress induced both the short- and long-term anxiety-like behaviors. However, triple sevoflurane exposures ameliorated the long-term anxiety-like behaviors induced by the foot shocks. In parallel, foot shocks stress upregulated the expression of phosphorylated extracellular ...

In particular, we are not interested in replacing the decision function in ProB with a predictor presented in this paper. The goal is to find subsets of the B language in which a backend performs better than others to strengthen our knowledge of the different tools at hand. With the ...
Adding a tolerance won't work very well here because the noise in the results is still quite high and will continue to be high unless we use large enough graphs and small enough cut probabilities that the computation time becomes too long for a test. Member szhorvat commented Nov 7, 2024...
