描述----------Description----------
Creates the overall test statistics for an Aalen additive regression model
创建一个阿伦添加剂回归模型的整体测试统计
用法----------Usage----------
## S3 method for class 'aareg'
summary(object, maxtime, test=c("aalen", "nrisk"), scale=1,...)
参数----------Arguments----------
参数:object
the result of a call to the aareg function
aareg函数调用的结果
参数:maxtime
truncate the input to the model at time "maxtime"
截断模型“maxtime”的输入
参数:test
the relative time weights that will be used to compute the test
相对的时间将被用来计算测试重量
参数:scale
scales the coefficients. For some data sets, the coefficients of the Aalen model will be very small (10-4); this simply multiplies the printed values by a constant, say 1e6, to make the printout easier to read.
尺度系数。对于一些数据集,的阿伦模型的系数将是非常小的(10-4);这只是印刷值乘以一个常数,说1E6,使打印更容易阅读。
参数:...

详情----------Details----------
It is not uncommon for the very right-hand tail of the plot to have large outlying values, particularly for the standard error. The maxtime parameter can then be used to truncate the range so as to avoid these. This gives an updated value for the test statistics, without refitting the model.
这并非罕见的图,有大量的外围值非常右手的尾巴,特别是对标准的错误。 maxtime参数可以被用来截断的范围,以避免这些。这给出了一个测试统计值更新,无需改装模型。
值----------Value----------
a list is returned with the following components
以下组件返回列表
参数: table
a matrix with rows for the intercept and each covariate, and columns giving a slope estimate, the test statistic, it's standard error, the z-score and a p-value
与拦截和每个协行,给人一种斜率估计的列的矩阵,检验统计量,它是标准的错误,Z-得分和p值
参数: test
the time weighting used for computing the test statistics
时间加权计算测试统计
参数: test.statistic
the vector of test statistics
检验统计量的矢量
参数: test.var
the model based variance matrix for the test statistic
基于模型试验统计方差矩阵
参数: test.var2
optionally, a robust variance matrix for the test statistic
可选,为检验统计量的稳健的方差矩阵
参数: chisq
the overall test (ignoring the intercept term) for significance of any variable
任何变量的意义整体测试(忽略截距项)
参数: n
a vector containing the number of observations, the number of unique death times used in the computation, and the total number of unique death times
矢量包含的若干意见,独特的死亡人数在计算中使用的时间,总数独特的死亡时间
