### First parts of Data.
head(ex_dta)
### Obtain PSs.

v_grp = "Group", cur_grp_level = "current",
ps_method = "logistic", nstrata = 5)
### Balance assessment of PS stratification.
### See "sec_4_1_ex" for details.
### Obtain discounting parameters.
### See "sec_4_1_ex" for details.
ps_bor_single <- psrwe_borrow(dta_ps_single, total_borrow = 30)
### PSKM, single arm study, time-to-event outcome.
rst_km <- psrwe_survkm(ps_bor_single,
v_time = "Y_Surv",
v_event = "Status",

### Plot PSKM
plot(rst_km)
plot(rst_km, add_ci = FALSE, add_stratum = TRUE)
plot(rst_km, conf_type = "plain")
### Outcome analysis.
oa_km <- psrwe_outana(rst_km, mu = 0.70, alternative = "greater")
