描述----------Description----------
This class of objects is returned by the survfit class of functions to represent a fitted survival curve.
这一类的对象,则返回survfit功能的类代表拟合生存曲线。
Objects of this class have methods for the functions print, summary, plot, points and lines. The print.survfit method does more computation than is typical for a print method and is documented on a separate page. Class of objects that represent a fitted survival curve.
这个类的对象的功能的方法print,summary,plot,points和lines。 print.survfit方法做更多的计算,比典型的打印方法,是一个单独的页面上记录。类的对象表示拟合生存曲线。
参数----------Arguments----------
参数:n
total number of subjects in each curve.
曲线中每个科目的总数。
参数:time
the time points at which the curve has a step.
在该曲线有一个步骤的时间点。
参数:n.risk
the number of subjects at risk at t.
在t风险科目。
参数:n.event
the number of events that occur at time t.
在t时刻发生的事件的数目。
参数:n.enter
for counting process data only, the number of subjects that enter at time t.
点票过程数据,进入科目,在时间t的数量。
参数:n.censor
for counting process data only, the number of subjects who exit the risk set, without an event, at time t. (For right censored data, this number can be computed from the successive values of the number at risk).
点票过程数据,退出的风险,没有一个事件,在时间t,集数学科。 (右删失数据,这个数字可以从风险的连续值计算)。
参数:surv
the estimate of survival at time t+0. This may be a vector or a matrix.
估计在时间T +0的生存。这可能是一个向量或矩阵。
参数:std.err
the standard error of the cumulative hazard or -log(survival).
累积性危害或日志(生存)的标准错误。
参数:upper
upper confidence limit for the survival curve.
生存曲线的置信上限。
参数:lower
lower confidence limit for the survival curve.
生存曲线较低的置信下限。
参数:strata
if there are multiple curves, this component gives the number of elements of the time etc. vectors corresponding to the first curve, the second curve, and so on. The names of the elements are labels for the curves.
如果有多个曲线,这个组件提供了time等向量对应的第一条曲线,二次曲线,等元素的数量。元素的名称是曲线的标签。
参数:start.time
the value specified for the start.time argument, if it was used in the call.
指定start.time参数,如果是在通话中使用的值。
参数:n.all
for counting process data, and any time that the start.time argument was used, this contains the total number of observations that were available. Not all may have been used in creating the curve, in which case this value will be larger than n above. of observations that were available
点票过程的数据,任何时间,start.time参数,这包含了现有的观测总数。并非所有的可能已被用于创建曲线,在这种情况下,这个值会比n以上。现有的观测
参数:conf.type
the approximation used to compute the confidence limits.
逼近用于计算置信限。
参数:conf.int
the level of the confidence limits, e.g. 90 or 95%.
信心的限制,例如水平90或95%。
参数:na.action
the returned value from the na.action function, if any. It will be used in the printout of the curve, e.g., the number of observations deleted due to missing values.
返回值从na.action功能,如果有的话。将用于打印输出的曲线,如,由于缺失值的若干意见中删除。
参数:call
an image of the call that produced the object.
调用产生的对象的图像。
参数:type
type of survival censoring.
类型的生存审查。
结构----------Structure----------
The following components must be included in a legitimate survfit object.
在一个合法的survfit对象,必须包含以下组件。
标----------Subscripts----------
Survfit objects that contain multiple survival curves can be subscripted. This is most often used to plot a subset of the curves. Usually a single subscript will be used. In one particular case – survival curves for multiple covariate values, from a Cox model that includes a strata statement – there is a matrix of curves and 2 subscripts may be used. (In this case summary.survfit will also print the data as a matrix).
包含多个生存曲线survfit对象可以是下标。这是最常用的绘制曲线的一个子集。通常是一个单一的标将被使用。在一个特定的情况下 - 多个协变量的值,从Cox模型,其中包括一个strata语句,生存曲线 - 曲线和2标有一个矩阵可以使用。 (在这种情况下summary.survfit也将打印数据矩阵)。
