  2. 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]

  3. Strabismus surgery - Wikipedia

    en.wikipedia.org/wiki/Strabismus_surgery

    Strabismus surgery is a one-day procedure that is usually performed under general anesthesia most commonly by either a neuro- or pediatric ophthalmologist. [1] The patient spends only a few hours in the hospital with minimal preoperative preparation. After surgery, the patient should expect soreness and redness but is generally free to return home.

  4. Holm–Bonferroni method - Wikipedia

    en.wikipedia.org/wiki/Holm–Bonferroni_method

    The simple Bonferroni correction rejects only null hypotheses with p-value less than or equal to , in order to ensure that the FWER, i.e., the risk of rejecting one or more true null hypotheses (i.e., of committing one or more type I errors) is at most . The cost of this protection against type I errors is an increased risk of failing to reject ...

  5. Error correction model - Wikipedia

    en.wikipedia.org/wiki/Error_correction_model

    The cointegration test on does not follow a standard distribution The validity of the long-run parameters in the first regression stage where one obtains the residuals cannot be verified because the distribution of the OLS estimator of the cointegrating vector is highly complicated and non-normal

  6. Dunnett's test - Wikipedia

    en.wikipedia.org/wiki/Dunnett's_test

    Dunnett's test's calculation is a procedure that is based on calculating confidence statements about the true or the expected values of the differences , thus the differences between treatment groups' mean and control group's mean. This procedure ensures that the probability of all statements being simultaneously correct is equal to a specified ...

  7. Minnesota Paper Form Board Test - Wikipedia

    en.wikipedia.org/.../Minnesota_Paper_Form_Board_Test

    Minnesota Paper Form Board Test is said to test “imagery capacity” , [1] “ spatial visualization ”, [2] “mental visualization skills” [3] “part–whole relationship skills” [4] and “the ability of an individual to visualize and manipulate objects in space”. [5] The test consists of five figures and one of the figures ...

  8. Pressure-correction method - Wikipedia

    en.wikipedia.org/wiki/Pressure-correction_method

    The correction for the velocity that is obtained from the second equation one has with incompressible flow, the non-divergence criterion or continuity equation. is computed by first calculating a residual value , resulting from spurious mass flux, then using this mass imbalance to get a new pressure value. The pressure value that is attempted ...
