Approximate Vs. Monte Carlo Critical Values For The Winsorized T-Test
… it has been accepted practice for critical values for the Winsorized t test for independent samples to be based on adjusted degrees of freedom depending on the number of total non-Winsorized (approximate) values. Recently, a new such table of Winsorized critical values has been …

The dependent samples t and wilcoxon sign rank maximum test
… Statistical Libraries (IMSL, 1980). Two tailed critical values were derived from a mixed normal distribution. Critical values obtained were at the 0.05, 0.025, 0.01 and 0.005 alpha levels via sample sizes (n) 8 through 30, 45, 60, 90 and 120. Critical values were compared to values obtained …

Configuration spaces of thick particles on graphs
… vary. We show that there are finitely many critical values where the homotopy type of these spaces changes, and describe these critical values in terms of metric properties of the graph. This provides an upper bound on the number of critical values in terms of the metric data. Moreover, we …

A study of some life testing distributions
… powerful goodness-of-fit statistics. Tables of critical values are given for complete and censored samples when the hypothesis to be tested is completely specified or when the composite hypothesis of normality or exponentiality is to be tested. The third article gives some results on simple, …

Developing tools to identify factors that limit production in coastal marshes
… or expensive for wide-spread, regular use. Critical values of elemental concentrations in plant tissue are widely used to diagnose mineral deficiencies and toxicities in agricultural crops, however. I used the chemical composition of leaf tissue from S. patens grown under controlled …

Modeling and Analysis of a Moving Conductive String in a Magnetic Field
… first considered in a static setting. Stability critical values of the magnetic field, pulling speed, and current are shown to exist when the uniform motion (along a string line) of the string buckles into spiral forms. In the dynamic setting, conditions for stability of certain solutions are …

Inference for Parametric Empirical Processes
… straightforward calculation of approximate critical values in a variety of cases. Chapter 3 extends this methodology in a different direction, to two-sample tests of stochastic dominance. Tests for any order of dominance are considered, and the distribution of test statistics is shown to be …

CONFIDENCE REGIONS FOR OPTIMAL CONTROLLABLE VARIABLES FOR THE ROBUST PARAMETER DESIGN PROBLEM
… of noise variables, we show how to construct critical values needed to maintain the simultaneous coverage rate. Two examples are provided as a demonstration of the practical need to adjust the critical values for simultaneous coverage. The zero-gradient confidence region only focuses on the …

Some statistical problems in sequential meta-analysis
… show that the use of Gombay method with critical values derived from asymptotic theory does not control the Type I error. However, the test with bootstrap-based critical values (retrospective Gombay sequential bootstrap test for REM) leads to a reduction of the difference between the true …

Behavior of partition values modulo powers of primes
… to define, questions on the arithmetic of its values lie much deeper. Ninety years ago, Ramanujan proved the celebrated congruences for <italic>p(n)</italic> which bear his name. For example, he proved, for all <italic>n</italic>, that <italic>p(5n + 4) == 0 mod 5</italic>. Work of Ono and …

Phase transition of a vector operator in AdS-CFT
… phase transitions when we adjust K through some critical values. Interestingly, we also found that depending on the conformal dimension of the operator, the transitions in transverse and longitudinal directions may behave in the same way, or in the opposite way.

A robustness type optimality criterion for experimental design
… is studied through the dependence of the tests' critical values on the regression variables, when the data originate from a non-normal parent. It is proved that the robustness of the tests' critical values to the assumption of non-normality can be improved through an adequate choice of the design …

Unobserved heterogeneity in economic models: testing and estimation
… the use of a bootstrap method to determine critical values that are shown to work better than the asymptotic critical values in finite samples and consistency of the bootstrap procedure is formally proved. We compare performance of the likelihood ratio test with that of the $C(\alpha)$ test …

A stepwise test characteristic curve method to detect item parameter drift
… based on TCC without requirement to set any critical values. Comparisons were made between the new method and two commonly used existing methods under the three-parameter logistic model. Results show that the new method performed well in IPD detection.
