  2. Marginal zone - Wikipedia

    en.wikipedia.org/wiki/Marginal_zone

    The marginal zone is the region at the interface between the non-lymphoid red pulp and the lymphoid white-pulp of the spleen. (Some sources consider it to be the part of red pulp which borders on the white pulp, while other sources consider it to be neither red pulp nor white pulp.) A marginal zone also exists in the lymphoid follicles of lymph ...

  3. Radial unit hypothesis - Wikipedia

    en.wikipedia.org/wiki/Radial_unit_hypothesis

    The Radial Unit Hypothesis (RUH) is a conceptual theory of cerebral cortex development, first described by Pasko Rakic. It states that the cerebral cortex develops during embryogenesis as an array of interacting cortical columns , or 'radial units', each of which originates from a transient stem cell layer called the ventricular zone , which ...

  4. McNemar's test - Wikipedia

    en.wikipedia.org/wiki/McNemar's_test

    McNemar's test is a statistical test used on paired nominal data.It is applied to 2 × 2 contingency tables with a dichotomous trait, with matched pairs of subjects, to determine whether the row and column marginal frequencies are equal (that is, whether there is "marginal homogeneity").

  5. Marginal-zone B cell - Wikipedia

    en.wikipedia.org/wiki/Marginal-zone_B_cell

    In humans the splenic marginal zone B cells have evidence of somatic hypermutation in their immunoglobulin genes, indicating that they have been generated through a germinal centre reaction to become memory cells. While naive MZ B cells produce low-affinity IgM antibodies, memory MZ B cells express high-affinity Ig molecules.

  6. Multivariate normal distribution - Wikipedia

    en.wikipedia.org/wiki/Multivariate_normal...

    The null hypothesis is that the data set is similar to the normal distribution, therefore a sufficiently small p-value indicates non-normal data. Multivariate normality tests include the Cox–Small test [ 33 ] and Smith and Jain's adaptation [ 34 ] of the Friedman–Rafsky test created by Larry Rafsky and Jerome Friedman .

  7. Analysis of competing hypotheses - Wikipedia

    en.wikipedia.org/wiki/Analysis_of_competing...

    Heuer outlines the ACH process in considerable depth in his book, Psychology of Intelligence Analysis. [1] It consists of the following steps: Hypothesis – The first step of the process is to identify all potential hypotheses, preferably using a group of analysts with different perspectives to brainstorm the possibilities.

  8. Marginal likelihood - Wikipedia

    en.wikipedia.org/wiki/Marginal_likelihood

    A marginal likelihood is a likelihood function that has been integrated over the parameter space.In Bayesian statistics, it represents the probability of generating the observed sample for all possible values of the parameters; it can be understood as the probability of the model itself and is therefore often referred to as model evidence or simply evidence.

  9. Cajal–Retzius cell - Wikipedia

    en.wikipedia.org/wiki/Cajal–Retzius_cell

    Cajal–Retzius cells were described to migrate tangentially in the marginal zone, a superficial layer of the preplate in the cortical neuroepithelium, [3] [4] According to some studies, this migration depends on the site where the cell was generated, showing a link between the origin, the migration and the destination of the cell.
