quasinormal subgroups have been studied for nearly 80 years. in finite groups, questions concerning them invariably reduce to p-groups, and here they have the added interest of being invariant under projectivities, unlike normal subgroups. however, it has been shown recently that certain groups, constructed by berger and gross in 1982, of an important universal nature with regard to the existen...

statistical errors are common in scientific literature and about 50% of the published articles have at least one error. the assumption of normality needs to be checked for many statistical procedures, namely parametric tests, because their validity depends on it. the aim of this commentary is to overview checking for normality in statistical analysis using spss.

In this paper, I will investigate the potential of what term Merleau-Ponty’s ‘situated phenomenology’ for an investigation normality from within and without. First, argue that concept situation in Phenomenology Perception demarcates turn a mere epistemological to concrete critical phenomenology. Second, apply as being situated normality. doing so, endeavor differentiate between lived represente...

A topological space X is C-κ-normal (C-mildly normal ) if there exist a κ-normal (mildly normal) Y and bijective function f : → such that the restriction f|A A→ f(A) homeomorphism for each compact subspace ⊆ X. We present new results about those two properties use discrete extension to solve open problems regarding C2-paracompactness α-normality

This paper studies design schemes for the X control chart under non-normality. Different estimators of the standard deviation are considered and the effect of the estimator on the performance of the control chart under non-normality is investigated. Two situations are distinguished. In the first situation, the effect of non-normality on the X control chart is investigated by using the control l...

This article proposes ‘nearly mobile’ as a productive concept to illustrate the im/mobility experiences amongst Asian skilled migrants in England during global health crisis. The of describes how mobility practices and aspirations have been heavily restricted national lockdowns, while still remaining fluid relational, with both debilitating empowering potentials. ambiguity ‘nearly’ offers frust...

We develop a test for equality of variances given two independent random samples of observations. The test can be expected to perform well when both sample sizes are at least moderate and the sample variances are asymptotically equivalent to the maximum likelihood estimators of the population variances. The test is motivated by and is here assessed for the case when both populations sampled are...

We consider semiparametric fractional exponential (FEXP) estimators of the memory parameter for a potentially nonstationary linear long-memory time series with smooth additive trend. We use differencing to annihilate the trend, followed by tapering to handle the potential non-invertibility of the differenced series. We propose a method of pooling the tapered periodogram which leads to more effi...
