Relation between pre-and post-test probabilities for various likelihood ratio positives (upper left half) and various likelihood ratio negatives (lower right half). It is possible to do a calculation of likelihood ratios for tests with continuous values or more than two outcomes which is similar to the calculation for dichotomous outcomes.
In fact, post-test probability, as estimated from the likelihood ratio and pre-test probability, is generally more accurate than if estimated from the positive predictive value of the test, if the tested individual has a different pre-test probability than what is the prevalence of that condition in the population.

A current ratio lower than the industry average could mean the company is at risk for default, and in general, is a riskier investment. ... Current ratio vs. quick ratio vs. debt-to-equity.
Both the relative risk and odds ratio are relevant in retrospective cohort studies, but only the odds ratio can be used in case-control studies. Although most case-control studies are retrospective, they can also be prospective when the researcher still enrolls participants based on the occurrence of a disease as new cases occur.

Facilitation of excitatory post-synaptic current (EPSC) can be quantified as a ratio of subsequent EPSC strengths. Each EPSC is triggered by pre-synaptic calcium concentrations and can be approximated by: EPSC = k([Ca 2+] presynaptic) 4 = k([Ca 2+] rest + [Ca 2+] influx + [Ca 2+] residual) 4. Where k is a constant. Facilitation = EPSC 2 / EPSC ...
