LogRankTest

LogRankTest[{data1, data2, ...}] tests for equal hazard rates among the datai using a log-rank type test.

• LogRankTest[{data1, data2, ...}, wspec] performs a weighted log-rank test with weights wspec.
• LogRankTest[{data1, ...}, wspec, "property"] returns the value of "property".

Examples

Compare survival data:

data1 = {1, 2, 3, 5, 7};
data2 = {2, 4, 6, 8, 10};
LogRankTest[{data1, data2}]

Get p-value:

LogRankTest[{data1, data2}, Automatic, "PValue"]

Weighted test:

LogRankTest[{data1, data2}, "Prentice"]
