Next: CR Bound for Up: Cram?r-Rao Bound - Accuracy Previous: Introduction . ... The left side of (1) is the mean square error for the estimate and the right side is the bound. No estimate for a can have a mean square error smaller than the bound. From (1) we observe the following regarding changes in a : if the PDF change is large the error will be small; if, however, the PDF change is small the error is large. The CR bound estimates the sensitivity of the data to changes in a . ...

... Thomson's multiple window method of spectral estimationthomson provides a very good estimate of the power spectrum by measuring the energy contained within a collection of rectangular shaped frequency intervals. ... Often, much of the fine structure of a spectral estimate is due to noise. It should be stressed that while other methods of spectral estimation (such as the Welchoppenheim method) exist, the Thomson method is particularly noteworthy for its precisely defined rectangular frequency bins. ...

... Data extracted from CCD frames may be accompanied by error estimates, which can be used in determining weights in the general solution. These should be in the same intensity units as the data in the SIGNAL column. ... The column label for estimated errors is ESTERR. This column should not be used for ordinary photometric data (i.e., do not put estimates of ``photon noise'' here). ... If the data were expressed as magnitudes (column RAWMAG), any error estimates should also be in magnitudes. ...

... Countrates can, however, be estimated in a simple way, but with less accuracy than for example a maximum likelihood fitting method. Countrates are estimated using a countrate image. ... Multiplying this maximum correlation with gives an estimate for the source countrate. In a separate routine the best correlation for a given source for all different wavelet scales will be compared and the most appropriate wavelet scale will be used, in order to obtain the source countrate. ...

Estimates for the Set-theoretic Distance between Orbits of Celestial Bodies . ... It is reasonable to use preliminary simple criteria for the proximity to intersection based on estimates of set-theoretic distance ( , 0 ) between orbits , 0 of celestial bodies , 0 . ... We describe here two simple criteria and one more complicated one. ... The third one requires calculation of the distance itself and it amounts to solving a trigonometric equation of the 8-th degree. ...

... We demonstrate through numerical simulations that model parameters estimated with our technique are essentially bias-free, even when the average number of counts per bin is 1. ... The IW technique avoids such biases by estimating through successive iterations, where for each iteration, j, , and the best-fit parameters are determined by minimization of . ... In our sample, we find that the minimum values and best-fit parameters converge after about 6 iterations. ...

Next: BH+BH merging Up: The Present Situation in Previous: Observational Data .

Pulkovo NEO Page . ... NEA Accuracy Estimation . ... The estimation of accuracy of the current CCD observations of asteroids and comets is constantly performed at Pulkovo Observatory. ... The (O-C) values, so called "Observed" minus "Calculated" positions, characterize numerically the observations of any observatory, both professional and amateur, during a short period (one or several close nights). ... So the (O-C) values for these objects nearly entirely define the errors of observations. ...

The black hole (BH) masses in the centers of active galactic nuclei (AGNs) have been estimated for a sample of radio-selected, flat-spectrum quasars to investigate the relationship between BH mass and radio properties of quasars. ... In contrast to previous studies, we find no correlation between BH mass and radio power in these AGNs. We find a range in BH mass similar to that seen in radio-quiet quasars from previous studies. ... You can now find me in room 99 at Epping. ...

... The Round Earth . ... Aristarchus around 270 BC derived the Moon's distance from the duration of a lunar eclipse (Hipparchus later found an independent method). ... Let R be the radius of that circle and T the time it takes the Moon to go around once, about one month. ... Viewed from Earth, a "new Moon" (occuring between the time a thin crescent is last seen before sunrise and the time one is seen shortly after sunset) happens when the Moon in its apparent motion around the sky overtakes the Sun. ...

... The greater the distance, the smaller the parallax. ... That triangle has the same proportions as the much larger triangle ABC, and therefore, if the distance B'C to the thumb is 10 times the distance A'B' between the eyes, the distance AC to the far landmark is also 10 times the distance AB. ... The most distant objects our eyes can see are the stars, and they are very far indeed: light which moves at 300,000 kilometers (186,000 miles) per second, would take years, often many years, to reach them. ...

... 3) Decide which scans were off-Fringe and use them to estimate the background noise. 4) For the on-Fringe scans, estimate the mean square power (per wavenumber bin), subtract the off-Fringe power, and if you have courage, take the square root. ... Some disadvantages of this procedures are: You have to have a good estimate of the off-Fringe noise power; if the nominal signal/noise in a single wavenumber bin is small: (S/N)<1 , then the S/N of the correlated flux after M samples is only (S/N)^2 (M). ...
