conditional_surv_est.Rd
conditional_surv_est
estimates the KaplanMeier conditional survival at
fixed time points and produces a 95% confidence interval
conditional_surv_est(basekm, t1, t2)
basekm 


t1  the time on which to condition 
t2  the survival time to estimate 
A list where cs_est
is the conditional survival estimate,
cs_lci
is the lower bound of the 95
cs_uci
is the upper bound of the 95
For example, if t1
= 2 and t2
= 5, the function
will return the probability of surviving to year 5 conditioned on having
already survived to year 2. See the vignette
at http://www.emilyzabor.com/condsurv/articles/estimate_cs.html for
details on calculations of conditional survival estimates and confidence
intervals, and examples.
