permlogrank function

Permutation version of survdiff

Small sample survdiff using permutation reference distributions.

permlogrank(formula, data, subset, na.action, rho=0, nperm=5000)

Arguments

• nperm: number of permutations for the reference distribution
• formula, data, subset, na.action, rho: see survdiff for details

Details
