    Figure 1. View through 10 factor wedge prism of an "IN" tree. Figure 2. View through 10 factor wedge prism of a "Borderline" tree. Figure 3. View through 10 factor wedge prism of an "OUT" tree. The wedge prism is primarily used in a similar manner as an angle gauge in variable-radius plot sampling.

  4. Pentagrammic prism - Wikipedia

    en.wikipedia.org/wiki/Pentagrammic_prism

    It is a special case of a right prism with a pentagram as base, which in general has rectangular non-base faces. Topologically it is the same as a convex pentagonal prism . It is the 78th model in the list of uniform polyhedra , as the first representative of uniform star prisms , along with the pentagrammic antiprism , which is the 79th model.

  5. Bonferroni correction - Wikipedia

    en.wikipedia.org/wiki/Bonferroni_correction

    With respect to FWER control, the Bonferroni correction can be conservative if there are a large number of tests and/or the test statistics are positively correlated. [ 9 ] Multiple-testing corrections, including the Bonferroni procedure, increase the probability of Type II errors when null hypotheses are false, i.e., they reduce statistical ...
