Prism dioptres. Prism correction is commonly specified in prism dioptres, a unit of angular measurement that is loosely related to the dioptre. Prism dioptres are represented by the Greek symbol delta (Δ) in superscript. A prism of power 1 Δ would produce 1 unit of displacement for an object held 100 units from the prism. [2]
The Šidák correction is derived by assuming that the individual tests are independent. Let the significance threshold for each test be α 1 {\displaystyle \alpha _{1}} ; then the probability that at least one of the tests is significant under this threshold is (1 - the probability that none of them are significant).
The Mustard Procedure allows total correction of transposition of the great vessels. The procedure employs a baffle to redirect caval blood flow to the left atrium which then pumps blood to the left ventricle which then pumps the deoxygenated blood to the lungs. In a normal heart, de-oxygenated blood is pumped into the lungs via the right ...
The prism cover test ( PCT) is an objective measurement and the gold standard in measuring strabismus, i.e. ocular misalignment, or a deviation of the eye. [1] It is used by ophthalmologists and orthoptists in order to measure the vertical and horizontal deviation and includes both manifest and latent components. [1]
It has to be noted, though, that the iterative Cochrane–Orcutt procedure might converge to a local but not global minimum of the residual sum of squares. This problem disappears when using the Prais–Winsten transformation instead, which keeps the initial observation. See also. Hildreth–Lu estimation; Newey–West estimator
Women in Namibia face challenges in their health, gender based violence, and access to education.The government of Namibia is taking steps to provide women with equal rights to a degree that is largely unparalleled in Sub-Saharan Africa, including the promise of gender equality and increased parliament representation in the Namibian constitution.
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]
