  2. Bolometric correction - Wikipedia

    en.wikipedia.org/wiki/Bolometric_correction

    Bolometric correction. In astronomy, the bolometric correction is the correction made to the absolute magnitude of an object in order to convert its visible magnitude to its bolometric magnitude. It is large for stars which radiate most of their energy outside of the visible range. A uniform scale for the correction has not yet been standardized.

  3. Heckman correction - Wikipedia

    en.wikipedia.org/wiki/Heckman_correction

    The Heckman correction is a two-step M-estimator where the covariance matrix generated by OLS estimation of the second stage is inconsistent. [7] Correct standard errors and other statistics can be generated from an asymptotic approximation or by resampling, such as through a bootstrap. [8]

  4. Operation Scarlift - Wikipedia

    en.wikipedia.org/wiki/Operation_Scarlift

    Operation Scarlift. Operation Scarlift (also known as Project 500 or The Bond Issue Program [1]) was a program carried out by the Pennsylvania government in the 1960s and 1970s. [2] Its mission was to repair environmental damage caused by abandoned mine lands, acid mine drainage, and other issues associated with historic mining.

  5. Flat-field correction - Wikipedia

    en.wikipedia.org/wiki/Flat-field_correction

    This variation is called vignetting, and can be corrected by selectively brightening the perimeter of the image. Flat-field correction ( FFC) is a digital imaging technique to mitigate the image detector pixel-to-pixel sensitivity and distortions in the optical path. It is a standard calibration procedure in everything from personal digital ...

  6. Error correction model - Wikipedia

    en.wikipedia.org/wiki/Error_correction_model

    ECMs are a theoretically-driven approach useful for estimating both short-term and long-term effects of one time series on another. The term error-correction relates to the fact that last-period's deviation from a long-run equilibrium, the error, influences its short-run dynamics. Thus ECMs directly estimate the speed at which a dependent ...

  7. Greenhouse–Geisser correction - Wikipedia

    en.wikipedia.org/wiki/Greenhouse–Geisser...

    Greenhouse–Geisser correction. The Greenhouse–Geisser correction is a statistical method of adjusting for lack of sphericity in a repeated measures ANOVA. The correction functions as both an estimate of epsilon (sphericity) and a correction for lack of sphericity. The correction was proposed by Samuel Greenhouse and Seymour Geisser in 1959.

    Norfolk County Correctional Center. The Norfolk County Correctional Center is a house of correction located on the median of Route 128 in Dedham, Massachusetts. The facility has 502 beds and opened in 1992. [1] On average, there are 140 inmates who are serving sentences and 260 inmates waiting for trial. [1]

    The PRISMA flow diagram, depicting the flow of information through the different phases of a systematic review. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) is an evidence-based minimum set of items aimed at helping scientific authors to report a wide array of systematic reviews and meta-analyses, primarily used to assess the benefits and harms of a health care ...
