描述----------Description----------
Examine Within-Bin Treatment Differences on an Outcome Measure and Average these
检查内宾待遇上的差别,衡量的结果和平均这些
用法----------Usage----------
SPSoutco(dframe, trtm, qbin, yvar, 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 treatment factor variable.
处理因素变量的名称。
参数:qbin
Name of variable containing the PS bin number for each patient.

参数:yvar
Name of an outcome Y variable.
结果Y变量的名称。
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 an average or 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导致二进制指示器被处理作为一个连续变量来确定平均或比例。
Details
详细信息----------Details----------
Once the second phase of Supervised Propensity Scoring confirms, using SPSbalan(), that X-covariate Distributions have been Balanced Within-Bins, the third phase can start: Examining Within-Bin Outcome Difference due to Treatment and Averaging these Differences across Bins. Graphical displays of SPSoutco() results feature R barplot() invocations.
一旦确认,第二阶段的监督倾向评分使用SPSbalan(),X-协分布均衡的垃圾桶内,就可以开始第三阶段:检查在滨结果差异对因治疗,平均间的差异箱。图形显示的SPSoutco()的结果配:řbarplot()调用。
