The Keys to the White House. The Keys to the White House is a prediction system for determining the outcome of presidential elections in the United States. It was developed by American historian Allan Lichtman and Russian geophysicist Vladimir Keilis-Borok in 1981, adapting prediction methods that Keilis-Borok designed for earthquake prediction.
The following is an example of applying a continuity correction. Suppose one wishes to calculate Pr( X ≤ 8) for a binomial random variable X . If Y has a distribution given by the normal approximation, then Pr( X ≤ 8) is approximated by Pr( Y ≤ 8.5).
In mathematics, the discrete-time Fourier transform (DTFT) is a form of Fourier analysis that is applicable to a sequence of discrete values. The DTFT is often used to analyze samples of a continuous function. The term discrete-time refers to the fact that the transform operates on discrete data, often samples whose interval has units of time.
An amateur radio satellite is an artificial satellite built and used by amateur radio operators.It forms part of the Amateur-satellite service. [1] These satellites use amateur radio frequency allocations to facilitate communication between amateur radio stations.
Contents. Quantum computing. A quantum computer is a computer that exploits quantum mechanical phenomena. On small scales, physical matter exhibits properties of both particles and waves, and quantum computing leverages this behavior using specialized hardware.
Methamphetamine (METH) is a potent amphetamine-type stimulant that has high abuse potential and can be smoked, snorted, injected, or taken orally. The drug is high in lipid solubility and can cross the blood-brain barrier more readily than amphetamine due to the addition of an extra methyl group.
Probability theory. In probability theory and statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable. The general form of its probability density function is The parameter is the mean or expectation of the distribution (and also its median and mode), while ...
Accumulated cyclone energy (ACE) is a metric used to compare overall activity of tropical cyclones, utilizing the available records of windspeeds at six-hour intervals to synthesize storm duration and strength into a single index value. [1] The ACE index may refer to a single storm or to groups of storms such as those within a particular month ...
