print.KaplanMeier function

Print function for object of class 'KaplanMeier'

## S3 method for class 'KaplanMeier'
print(x, digits = 4, type = "risk", method = NULL, ...)

Arguments

• x: an object of class 'KaplanMeier'
• digits: number of digits to print the results
• type: either "surv" or "risk" (the default), depending on whether we want to print the results in terms of a survival probability or a risk (i.e., one minus the survival probability).
• method: either "EL", "Wald" or "both", depending on whether we want to print the results obtained when using empirical likelihood inference (EL), Wald-type inference (Wald) or both. Default is 'NULL', which means that 'method' inherits the value of the corresponding control parameter used when creating the object 'x'.
• ...: Not used

Returns

no return value, called for printing only.

Examples

# This example reproduces some results presented in Table 1 of Thomas and Grunkemeier (1975)
ResKM.1.95 <- KaplanMeier(time=Freireich$time[Freireich$group==1],
                          status=Freireich$status[Freireich$group==1],
                          t=10, level=0.95, contr=list(tol=1e-4))
print(ResKM.1.95, digits=3, type="surv", method="EL")   # EL results for survival
print(ResKM.1.95, digits=3, type="risk", method="Wald") # Wald results for risk
