... Posts tagged ?spatial statistics? ... As a part of exploring spatial distribution of particles/objects, not to approximate via Poisson process or Gaussian process (parametric), nor to impose hypotheses such as homogenous, isotropic, or uniform, various nonparametric methods somewhat dragged my attention for data exploration and preliminary analysis. ... I decide to discuss Kalman Filter a while ago for the slog after finding out that this popular methodology is rather underrepresented in astronomy. ...

Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

... The question which method of the detection of features in the test statistic is the most sensitive, is of considerable importance for all practical TSA applications. ... A power of the test statistic is the probability that is accepted for the given Y : . ... Then, all statistics based on models with 3 parameters have similar values of the test power: power spectrum, Scargle statistics, fit of a sinusoid, AOV(3) statistic and PDM(3) statistic with corrected probability distribution. ...

Observing Facilities . ... Observing with ESO Telescopes . ... However, if you want to process science data from different nights together you should limit the available calibrations to those from one night as the pipeline assumes that the calibration data were taken without mask movement in between. ...

... On-the-Fly Reprocessing . ... STIS has moved from the On-the-Fly Calibration (OTFC) processing system to the new On-the-Fly Reprocessing (OTFR) system. ... With OTFR, raw data headers are re-built from these pod files, enabling many changes and fixes to be done at this early step, which were impossible with OTFC. ... There will no longer be a column for Used and Best reference files, since you will by default receive the best reference files, and Used becomes meaningless under the OTFR system. ...

... PPTA timeline . ... List of projects . ... RedGW . ... One of the main goals of pulsar timing array projects is to limit the existence of a background of gravitational waves (GWs). Jenet et al. (2006) developed a method to determine such a limit if (and only if) the pulsar timing residuals were statistically white. In the paper we used data from six pulsars from the PPTA project to obtain a limit. The remaining pulsars were rejected because their timing residuals were not white. ...

... flspec computes the spectrum of the background fluctuations in EPIC Imaging data in different offaxis annular regions. ... Once the 'flatfielded' image is free from detected sources, its pixels are binned according to the input parameter binsize and classified as 'positive' (if they have more counts than the median in the image) and 'negative' pixels (less counts than the median). ... The positive and negative spectra are extracted with an spectral binning of 15 eV (MOS) and 5 eV (PN). ...

... Chapter 14. ... Data consist of numbers, of course. ... In the following sections, you will repeatedly encounter the following paradigm: § apply some formula to the data to compute a statistic § compute where the value of that statistic falls in a probability distribution that is computed on the basis of some null hypothesis § if it falls in a very unlikely spot, way out on a tail of the distribution , conclude that the null hypothesis is false for your ... 609 610 Chapter 14. ...

... The procedure of radiometer signal integration can be considered as a sort of reducing dimension of the initial sampling space, where the samples are the result of analog-to-digital conversion. ... The probability distribution of the signal and spikes is completely known. ... The quality of the considered algorithm could be also illustrated by Figure 2 . ... One could see the considered adaptive algorithm is preferable even by low degree of compression, because all spikes have been depressed. ...

... Moscow, Russia E-mail: krivosheev@iki.rssi.ru Notes: · · The Monte Carlo method (s) is also called the statistical test method An innumerable number of processes can be listed the outcome of which is not determined and has probabilistic nature, but these processes obey statistical laws, so to obtain the result we have to make multiple similar tests, i.e. to use the MC method Because probabilistic processes are widely spread in nature, the MC ...
