Definition. The false positive rate is = +. where is the number of false positives, is the number of true negatives and = + is the total number of ground truth negatives.. The level of significance that is used to test each hypothesis is set based on the form of inference (simultaneous inference vs. selective inference) and its supporting criteria (for example FWER or FDR), that were pre ...
The first documented use of the phrase "United States of America" is a letter from January 2, 1776. Stephen Moylan, a Continental Army aide to General George Washington, wrote to Joseph Reed, Washington's aide-de-camp, seeking to go "with full and ample powers from the United States of America to Spain" to seek assistance in the Revolutionary War effort.
Sensitivity (true positive rate) is the probability of a positive test result, conditioned on the individual truly being positive. Specificity (true negative rate) is the probability of a negative test result, conditioned on the individual truly being negative. If the true status of the condition cannot be known, sensitivity and specificity can ...
Neutral rate of interest. The neutral rate of interest, previously called the natural rate of interest, [1] is the real (net of inflation) interest rate that supports the economy at full employment /maximum output while keeping inflation constant. [2] It cannot be observed directly.
The acceptable quality limit ( AQL) is the worst tolerable process average ( mean) in percentage or ratio that is still considered acceptable; that is, it is at an acceptable quality level. [1] Closely related terms are the rejectable quality limit and rejectable quality level (RQL). [1] [2] In a quality control procedure, a process is said to ...
Failure rate. Failure rate is the frequency with which an engineered system or component fails, expressed in failures per unit of time. It is usually denoted by the Greek letter λ (lambda) and is often used in reliability engineering . The failure rate of a system usually depends on time, with the rate varying over the life cycle of the system.
The environmental lapse rate (ELR), is the rate of decrease of temperature with altitude in the stationary atmosphere at a given time and location. As an average, the International Civil Aviation Organization (ICAO) defines an international standard atmosphere (ISA) with a temperature lapse rate of 6.50 °C/km [15] (3.56 °F or 1.98 °C/1,000 ...
Case fatality rate. In epidemiology, case fatality rate ( CFR) – or sometimes more accurately case-fatality risk – is the proportion of people who have been diagnosed with a certain disease and end up dying of it. Unlike a disease's mortality rate, the CFR does not take into account the time period between disease onset and death.
