描述----------Description----------
Test for Conditional Independence of X-covariate Distributions from Treatment
测试条件独立的X-协处理分派
用法----------Usage----------
SPSbalan(dframe, trtm, qbin, xvar, faclev=3)
参数----------Arguments----------
参数:dframe
Name of augmented data.frame written to the appn="" argument of SPSlogit().
增强的数据框的名称写的APPN =“”的说法的SPSlogit()。
参数:trtm
Name of the two-level treatment factor variable.
两个级别的处理因素变量的名称。
参数:qbin
Name of variable containing bin numbers.
名称的变量含区号码。
参数:xvar
Name of one baseline covariate X variable used in the SPSlogit() PS model.
一个基线协变量X变量SPSlogit(PS)模式中使用的名称。
参数:faclev
Maximum number of different numerical values an X-covariate can assume without automatically being converted into a "factor" variable; faclev=1 causes a binary indicator to be treated as a continuous variable determining a proportion.
的最大数目的不同的数值的X-协变量可以假设没有自动被转换成一个“因子”变量; faclev = 1被处理作为一个连续变量确定的比例导致二进制指示器。
Details
详细信息----------Details----------
The second step in Supervised Propensity Scoring analyses is to verify that baseline X-covariates have the same distribution, regardless of treatment, within each fitted PS bin.
监督的倾向评分分析的第二个步骤是,以确认基线X-协变量有相同的分布,无论治疗,在每个安装的PS垃圾桶。
