For example, as statistical offices improve their data, measurement error decreases, so the error term declines over time.

When the brain is led to believe that the saccades it is generating are too large or too small ( by an experimental manipulation in which a saccade-target steps backwards or forwards contingent on the eye movement made to acquire it ), saccade amplitude gradually decreases ( or increases ), an adaptation ( also termed gain adaptation ) widely seen as a simple form of motor learning, possibly driven by an effort to correct visual error.

The viewfinder of a rangefinder camera is necessarily offset from the taking lens, so that the image shown is not exactly what will be recorded on the film ; this parallax error is negligible at large subject distances, but increases as the distance decreases.

The idea is that while there are composite probable primes to base a for any fixed a, we may hope there exists some fixed P < 1 such that for any given composite n, if we choose a randomly the probability that n is pseudoprime to base a is at most P. If we repeat this test k times, choosing a new a each time, the probability of n being pseudoprime to all the as tested is hence at most P < sup > k </ sup >, and as this decreases exponentially, only moderate k is required to make this probability negligibly small ( compared to, for example, the probability of computer hardware error ).

Finally, the " circular error " of a pendulum decreases as length of the swing decreases, so better clock escapements could greatly reduce this source of inaccuracy.

If the validation error increases ( positive slope ) while the training error steadily decreases ( negative slope ) then a situation of overfitting may have occurred.

As more redundant reference points are added the position fix becomes more accurate and the area of the resulting error ellipse decreases.

which decreases as and the familiar law of random walk applies: to reduce the error by a factor of 10 requires a 100-fold increase in the number of sample points.

The tolerable error decreases as nominal quantity increases, and is done by alternating intervals where there is a fixed error ( and thus over the interval the percentage error decreases ) with intervals where there is a percentage error.

Error tolerance decreases as nominal quantity increases, by alternating intervals of a given percent error with intervals of a given amount error: these interpolate between the stair-step decreases in percentage error.

If the drift error is systematic, it can be canceled with a bias circuit which can be arranged and adjusted to supply the required compensating current.

Dr. H. V. Hilprecht, Professor of Assyrian at the University of Pennsylvania, dreamed that a Babylonian priest, associated with the king Kurigalzu, ( 1300 B.C. ) escorted him to the treasure chamber of the temple of Bel, gave him six novel points of information about a certain broken relic, and corrected an error in its identification.

He contends this idea doesn't conflict with experiments on which the principle of conservation of matter and energy is based because some slight error must be assumed in such experiments.

Random error is typically assumed to be normally distributed with zero mean and a constant variance.

Nowadays most commercial planes are equipped with aircraft flight control systems in order to reduce pilot error and workload at landing or takeoff.

One problem with sports arbitrage is that bookmakers sometimes make mistakes and this can lead to an invocation of the ' palpable error ' rule, which most bookmakers invoke when they have made a mistake by offering or posting incorrect odds.

This also includes any run ( or any subsequent run ) that scores on plays that result in outs with one out or a double play with none out if an error has extended the inning.

A runner who reaches on catcher's interference and subsequently scores with two outs scores an unearned run, but baserunners who subsequently score after the runner who has reached on catcher's interference exclusively on clean plays score earned runs ; the baserunner cannot be assumed to have been put out except for the error.

:( 3 ) pitcher, the catcher or any infielder handles a batted ball and puts out a preceding runner who is attempting to advance one base or to return to his original base, or would have put out such runner with ordinary effort except for a fielding error.

Note that, although rarely occurring, if a runner tags and advances from second base ( or, theoretically, from first base ) all the way to home and scores ( without an intervening error ) the batter is credited with a sacrifice fly.

In 1887, the stolen base was given its own individual statistical column in the box score, and was defined for purposes of scoring: "... every base made after first base has been reached by a base runner, except for those made by reason of or with the aid of a battery error ( wild pitch or passed ball ), or by batting, balks or by being forced off.

" The next year, it was clarified that any attempt to steal must be credited to the runner, and that fielders committing errors during this play must also be charged with an error.

There was clarification that a runner is credited with a steal if the attempt began before a battery error.

1904 saw an attempt to reduce the already wordy slew of rules governing stolen bases, with the stolen base now credited when "... the advances a base unaided by a base hit, a put out, ( or ) a fielding or batter error.

Power was given to the official scorer, in the event of a muff by the catcher in throwing, that in the judgment of the scorer the runner would have been out, to credit the catcher with an error, and not credit the runner with a stolen base.

In computational complexity theory, BPP, which stands for bounded-error probabilistic polynomial time is the class of decision problems solvable by a probabilistic Turing machine in polynomial time, with an error probability of at most 1 / 3 for all instances.

In computational complexity theory, BQP ( bounded error quantum polynomial time ) is the class of decision problems solvable by a quantum computer in polynomial time, with an error probability of at most 1 / 3 for all instances.

However, the team's history during that period was hardly one of futility, but was rather punctuated with some of the most memorable moments in World Series history, including Enos Slaughter's " mad dash " in, the " Impossible Dream " of, Carlton Fisk's home run in, and Bill Buckner's error in.

* Some curves that seem simple, such as the circle, cannot be described exactly by a Bézier or piecewise Bézier curve ; though a four-piece cubic Bézier curve can approximate a circle ( see Bézier spline ), with a maximum radial error of less than one part in a thousand, when each inner control point ( or offline point ) is the distance horizontally or vertically from an outer control point on a unit circle.

For example, use of ( which gives é, Latin lower-case E with acute accent, U + 00E9 in Unicode ) in an XML document will generate an error unless the entity has already been defined.

It should be noted that calculated fatality rates based on distance for bicycling ( as well as for walking ) can have an exceptionally large margin of error, since there are generally no annual registrations or odometers required for bicycles ( as there are with motor vehicles ), and this means the distance traveled must be estimated.

However, with robust error correction, and the possibility of external intervention, the common science fiction theme of robotic life run amok is unlikely in the near term.

This is called gating error and causes an average error in the calculated frequency of Δf = 1 /( 2 T < sub > m </ sub >), or a fractional error of Δf / f = 1 /( 2 f T < sub > m </ sub >) where T < sub > m </ sub > is the timing interval and f is the measured frequency.

Consequently, a realisation of the metre is usually delineated ( not defined ) today in labs as wavelengths of helium-neon laser light in a vacuum, the error stated being only that of frequency determination.

Although conversion from wavelengths to metres introduces an additional error in the overall length due to measurement error in determining the refractive index and the frequency, the measurement of frequency is one of the most accurate measurements available.

The first law was published in 1774 and stated that the frequency of an error could be expressed as an exponential function of the numerical magnitude of the error, disregarding sign.

The second law of error was proposed in 1778 by Laplace and stated that the frequency of the error is an exponential function of the square of the error.

A designer of a system that deals with sampling and reconstruction processes needs a thorough understanding of the signal to be sampled, in particular its frequency content, the sampling frequency, how the signal is reconstructed in terms of interpolation, and the requirement for the total reconstruction error, including aliasing, sampling, interpolation and other errors.

where the average is taken over observation time τ, the y ( t ) is the fractional frequency error at time t and τ is the observation time.

The relation between the number of fractional frequency samples and time error series is fixed in the relationship

It decodes calls and soundings sent by other stations and uses the Bit error rate to store a quality score for that frequency and sender-address.

* spread spectrum and ultrawideband techniques allow several transmitters to transmit in the same place on the same frequency with very little interference, typically combined with one or more error detection and correction techniques to fix all the errors caused by that interference.

A frequentist claim is made, that the long-term frequency of VaR breaks will equal the specified probability, within the limits of sampling error, and that the VaR breaks will be independent in time and independent of the level of VaR.

For example, the " Atención " station was thought to be from Cuba, as a supposed error allowed Radio Habana Cuba to be carried on the frequency.
