  2. Šidák correction for t-test - Wikipedia

    en.wikipedia.org/wiki/Šidák_correction_for_t-test

    Suppose when testing each hypothesis , the test statistic we use is . If these 's are independent, then a test for can be developed by the following procedure, known as Šidák correction. Step 1, we test each of m null hypotheses at level . Step 2, if any of these m null hypotheses is rejected, we reject. H n u l l {\displaystyle H_ {null}}

  3. Serial transverse enteroplasty - Wikipedia

    en.wikipedia.org/wiki/Serial_transverse_enteroplasty

    Serial transverse enteroplasty (STEP) is a surgical procedure used primarily in the treatment of short bowel syndrome (SBS). In STEP, by making cuts in the intestine and creating a zigzag pattern, surgeons lengthen the amount of bowel available to absorb nutrients. The procedure was first performed in 2003 and more than 100 patients had ...

    Hochberg's step-up procedure. Hochberg's step-up procedure (1988) is performed using the following steps: Start by ordering the p-values (from lowest to highest) () … and let the associated hypotheses be … ()

  5. 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]

  6. Flowchart - Wikipedia

    en.wikipedia.org/wiki/Flowchart

    A flowchart is a type of diagram that represents a workflow or process. A flowchart can also be defined as a diagrammatic representation of an algorithm, a step-by-step approach to solving a task. The flowchart shows the steps as boxes of various kinds, and their order by connecting the boxes with arrows.

  7. PISO algorithm - Wikipedia

    en.wikipedia.org/wiki/PISO_algorithm

    PISO algorithm ( Pressure-Implicit with Splitting of Operators) was proposed by Issa in 1986 without iterations and with large time steps and a lesser computing effort. It is an extension of the SIMPLE algorithm used in computational fluid dynamics to solve the Navier-Stokes equations. PISO is a pressure-velocity calculation procedure for the ...

  8. Scheffé's method - Wikipedia

    en.wikipedia.org/wiki/Scheffé's_method

    Scheffé's method is a single-step multiple comparison procedure which applies to the set of estimates of all possible contrasts among the factor level means, not just the pairwise differences considered by the Tukey–Kramer method. It works on similar principles as the Working–Hotelling procedure for estimating mean responses in regression ...

  9. Mustard procedure - Wikipedia

    en.wikipedia.org/wiki/Mustard_procedure

    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 ...
