Autocorrelation is the cross-correlation of a signal with itself.

* Autocorrelation is used to analyze Dynamic light scattering data, which notably enables to determine the particle size distributions of nanometer-sized particles or micelles suspended in a fluid.

* Autocorrelation in space rather than time, via the Patterson function, is used by X-ray diffractionists to help recover the " Fourier phase information " on atom positions not available through diffraction alone.

Autocorrelation is defined as the cross-correlation of the signal with itself over varying intervals of time or space.

Autocorrelation can be visualized on a data plot when a given observation is more likely to lie above a fitted line if adjacent observations also lie above the fitted regression line.

Autocorrelation may be the result of misspecification such as choosing the wrong functional form.

Autocorrelation of the errors, which themselves are unobserved, can generally be detected because it produces autocorrelation in the observable residuals.

Autocorrelation violates the ordinary least squares ( OLS ) assumption that the error terms are uncorrelated.

Autocorrelation of the signal can be analyzed in terms of the diffusion of the particles.

* Autocorrelation detects signal waveforms.

Autocorrelation methods need at least two pitch periods to detect pitch.

Autocorrelation analysis helps to identify the correct phase of the fitted model while the successive differencing transforms the stochastic drift component into white noise.

The men who speculate on these institutions have, for the most part, come to at least one common conclusion: that many of the great enterprises and associations around which our democracy is formed are in themselves autocratic in nature, and possessed of power which can be used to frustrate the citizen who is trying to assert his individuality in the modern world ''.

They all have this in common: the earth is situated near the center of the deferent.

But that one should superimpose all these charts, run a pin through the common point, and then scale each planetary deferent larger and smaller ( to keep the epicycles from ' bumping ' ), this is contrary to any intention Ptolemy ever expresses.

`` History has this in common with every other science: that the historian is not allowed to claim any single piece of knowledge, except where he can justify his claim by exhibiting to himself in the first place, and secondly to any one else who is both able and willing to follow his demonstration, the grounds upon which it is based.

To obey the moral law is just ordinary common sense, applied to a neglected field.

British common sense is proverbial.

I seized the rack and made a western-style flying-mount just in time, one of my knees mercifully landing on my duffel bag -- and merely wrecking my camera, I was to discover later -- my other knee landing on the slivery truck floor boards and -- but this is no medical report.
