The specificity of the test is equal to 1 minus the false positive rate. In statistical hypothesis testing, this fraction is given the Greek letter α, and 1 − α is defined as the specificity of the test. Increasing the specificity of the test lowers the probability of type I errors, but may raise the probability of type II errors (false ...
The false positive rate (false alarm rate) is = + [1]. where is the number of false positives, is the number of true negatives and = + is the total number of ground truth negatives.
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.
Although the term ‘objective test’ encompasses a wide range of tests with which most people are somewhat familiar (i.e. Wechsler Adult Intelligence Scale, Minnesota Multiphasic Personality Inventory, Graduate Record Examination, and the Standardized Achievement Test), it is a term that arose out of the field of personality assessment, as a ...
Test of variation in physiological measures An early warning system ( EWS ), sometimes called a between-the-flags or track-and-trigger chart , is a clinical tool used in healthcare to anticipate patient deterioration by measuring the cumulative variation in observations, most often being patient vital signs and level of consciousness.

A sample argument using objections. Some argument mapping conventions allow for perspicuous representation of inferences. [12] In the following diagram, box 2.1 represents an inference, labeled with the inference rule modus ponens. [12] An argument map with 'modus ponens' in the inference box. An inference can be the target of an objection.
In the law of the United States of America, an objection is a formal protest to evidence, argument, or questions that are in violation of the rules of evidence or other procedural law. Objections are often raised in court during a trial to disallow a witness's testimony, and may also be raised during depositions and in response to written ...
An inference objection is an objection to an argument based not on any of its stated premises, but rather on the relationship between a premise (or set of premises) and main contention. [ 4 ] [ 5 ] For a given simple argument, if the assumption is made that its premises are correct, fault may be found in the progression from these to the ...
