For one thing, the test is derived from material not covered at many middle schools — meaning it heavily favors affluent families who can provide their children with preparatory courses and with expensive tutors who are familiar with the test material.
The loading used in the tests was derived from a load spectrum representing the real operational conditions of the PZL I-22 Iryda aircraft.
The chi-square statistic for this test was derived as follows: mathrm{LR}kern0.24em mathrm{statistic}=-2left[ln {L}_{mathrm{T}}-left(ln {L}_{mathrm{p}}+ln {L}_{mathrm{T}mathrm{R}}right)right]sim {chi}_{mathrm{k}}^2 (6).
Critical values of the tests are derived from large sample considerations.
A linearized model of the testbed is derived for control design.
The tests are derived for a NARMAX (Non-linear Autor-Regressive Moving Average model with eXogenous inputs) filter design based on a Sub-Optimal Least Squares (SOLS) estimation algorithm.
The sensitivity of the PSA test was derived from the literature (Bretton, 1994; Imai et al, 1994, 1995; Jubelirer et al, 1994; Stenman et al, 1994; el-Galley et al, 1995; Higashihara et al, 1996; Brett, 1998; Gustafsson et al, 1998; Hoffman et al, 2002; Mistry and Cable, 2003).
The Modified Sorensen test was derived from Biering-Sorensen [ 23], who used this test to assess the isometric strength and endurance of the lumbar back extensors in individuals with low back pain.
The asymptotic efficiency of the Wilcoxon rank-sum test was derived and compared with that of the modified Wilcoxon rank-sum test for the LLD.
While the q p-values λi are obtained from the marginal permutation distribution of the first order tests, the p-value of the global test is derived from the permutation distribution of the second order test, which is related to the q-variate distribution in the first step.
