Statistics Definitions > The monotone likelihood ratio (MLR) represents a useful data generating process; one where there’s a clear relationship between the magnitude of observed variables and the probability distribution they are drawn from. This clear relationship makes many statistical processes ...
Likelihood ratio statistics in factorial designs are more flexible than Wald statistics in the sense of adapting to non-saturated designs by fitting only as many parameters as the model calls for. This leads to a significant gain in power. Here we propose likelihood ratio type statistics for ...
2018, Handbook of StatisticsQiang Wu, Paul Vos 6.1 Likelihood Ratio Test Likelihood ratio tests (LRTs) are as widely applicable as maximum likelihood estimation. Definition 12 The LRT statistic for testing H0 : θ∈Θ0 vs Ha:θ∈Θ0c is λ(x)=supΘ0L(θ|x)supΘL(θ|x),and an LRT...
(by definition), the likelihood ratio must be a fraction (i.e., 0 < Λ < 1). Thus, lower values of Λ lend greater support to H1. Under the assumptions of the null model H0, the asymptotic distribution of the statistic –2 log Λ is chi-squared with υ degrees of freedom (2.5....
LR = likelihood1 ratio = "the ratio of two probabilities of the same event under different hypotheses." If you can think of "evidence" as meaning information that might nudge your decision about some matter in one direction or the other, then the LR is the appropriate numerical summary of...

To test whether the IIA property holds, a Wald test and alikelihood ratio testwere carried out. Both the test statistics follow asymptotically a chi-square distribution with one degree of freedom under the null hypothesis that there is no difference between the value of the likelihood function wi...

The ratio of the likelihoods P(E|H)/P(E|H′) is what takes us from the ratio of the prior to the ratio of the posteriors. Therefore, it expresses the relative import of evidence E on these two hypotheses. That the likelihoods capture all needed information for evaluating the bearing ...
