描述----------Description----------
Fit semiparametric mixture PH cure model or AFT cure model
适合半参数混合PH治疗模式或AFT治疗的模型
用法----------Usage----------
smcure(formula, cureform, offset = NULL, data, na.action = na.omit, model = c("aft", "ph"), link = "logit", Var = TRUE, emmax = 50, eps = 1e-07, nboot = 100)
参数----------Arguments----------
参数:formula
a formula object, specifying the variables included in the latent on the right. The response must be a survival object as returned by the Surv function.
一个公式对象,指定包括在潜在右边的变量。返回的幸存者功能的反应必须是生存的对象。
参数:cureform
specifies the variables in the incidence.
指定变量的发病率。
参数:offset
variable(s) with coefficient 1 in PH model or AFT model
在PH模式或AFT模型系数为1的变量(S)
参数:data
a data.frame in which to interpret the variables named in the formula and cureform.
数据框,在其中名为的公式和cureform的解释变量。
参数:na.action
a missing-data filter function. By default na.action = na.omit.
丢失数据的过滤功能。由的默认na.action = na.omit。
参数:model
specifies your model, it can be "ph" or "aft"
指定的模型,也可以是“pH值”或“船尾”
参数:link
specifies the link in incidence part. The logit, probit or complementary loglog (cloglog) links are available. By default the logistic regression model is assumed link = "logit".
指定链接的发病部位。数,概率或互补loglog(cloglog)的链接。默认情况下,Logistic回归模型假设链接=“罗吉特”。
参数:Var
If it is TRUE, the program returns Std.Error by bootstrap method. If set to False, the program only returns estimators of coefficients. By default, Var = TRUE
如果是TRUE,程序返回Std.Error的引导方法。如果设置为False,程序只返回系数的估计。默认情况下,VAR = TRUE
参数:emmax
specifies the maximum iteration number. If the convergence criterion is not met, the EM iteration will be stopped after emmax iterations and the estimates will be based on the last maximum likelihood iteration. The default emmax = 100.
指定的最大迭代次数。如果不能满足收敛条件,EM迭代将停止emmax迭代后,将根据最后的最大似然迭代估计。的的默认emmax = 100。
参数:eps
sets the convergence criterion. The default is eps = 1e-7. The iterations are considered to be converged when the maximum relative change in the parameters and likelihood estimates between iterations is less than the value specified.
设置收敛标准。默认值是每股收益= 1E-7。迭代都被认为是会聚时,在参数和似然估计的迭代之间的最大相对变化小于指定的值。
参数:nboot
specifies the number of bootstrap sampling. The default nboot = 100.
指定bootstrap抽样的数量。的默认的nboot = 100。
