SO.LRT {CorrBin} | R Documentation |
SO.LRT
computes the likelihood ratio test statistic for stochastic
ordering against equality assuming marginal compatibility for both
alternatives. Note that this statistic does not have a
chi-squared distribution, so the p-value computation is not
straightforward. The SO.trend.test
function implements a
permutation-based evaluation of the p-value for the likelihood-ratio test.

The value of the likelihood ratio test statistic is returned with two attributes:
ll0 |
the log-likelihood under H0 (equality) |
ll1 |
the log-likelihood under Ha (stochastic order) |
