Summary of Survival Curve differences using G-rho tests
Description
Runs the log-rank test and Breslow test to test for difference between two or
more survival curves.
Usage
grhoTests(formula, data, digits = 4)
Arguments
formula
formula expression of the form Surv(time, status) ~ predictors
data
data frame where variables from formula originate
digits
number of significant digits to retain
Details
The log-rank test corresponds to rho = 0 and the Breslow test
corresponds to rho = 1 in survdiff. This function emulates the
"Overall Comparisons" table output from SPSS.
Value
The Chi-Square statistic, degrees of freedom, and p-value are given
for both G-rho tests.
