Right Heart Catheterization Data
Description
The data in the example are from Frank Harrell's Hmisc package.
The data there are very similar to the
data in Connors et al. (1996), but do not exactly reproduce analyses from
that article. So, we employ the version of that analysis in the
documentation for Ruoqi Yu's RBestMatch package,
which attempts to be close to the analysis in Connors et al.
In Yu's version, the propensity score (her
pr) is built using 76 covariates, and the focus of attention is on
26 "priority" covariates (her X) and the propensity score
that were emphasized in the Connors et al. article, including those in that
article's Table 3.
