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.
SO.LRT(cbdata, control = soControl())
cbdata |
a CBData object |
control |
an optional list of control settings, usually a call to soControl .
See there for the names of the settable control values and their effect. |
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) |
