Student's t-table modification for the linear correlation coefficients estimation in the small samples cases

In the linear correlation coefficient calculations for the statistical significance estimation is often used the famous Chaddock?s scale of the relationship between the studied phenomena with the characteristics like ?weak?, ?medium?, ?visible?, ?high?, ?very high?, and for the significance evaluati

The method of specification the degree of reliability for ?zero hypotheses" about the distribution laws basing on Pearson?s and Kolmogorov?s consent criteria.

In the recent years the modern socio-economic indicators usually are very unstable. Therefore the using of initial (raw) data even in the so-called "small samples" volume (25-30 values) could be problematic [1], [2]. For the initial data now it is often necessary to use the smaller number

В работе рассмотрены вопросы переходы от интервальной (количественной) шкалы в порядковую (лингвистическую), развивая тем самым некоторые предложения,указанные в [1],[2],[3].В качестве примера выступают ожидания от автомобилиста:10,0 км или 10,5 км? велика ли разница?В статье даётся определённый отв

Методика оценки значения частоты среза и запаса по фазе в системе автоматического управления

На примере отдельного звена системы автоматического управления (САУ) приведён способ точного получения частоты среза и запаса по фазе на совместных логарифмических амплитудных и частотных характеристиках (ЛАЧХ и ЛФЧХ). Точное значение частоты среза по ЛАЧХ и соответствующее ему точное значение запас

Modification of estimations for the theoretical distributions in the modern Russian economy conditions

In the modern practice a number of variation series alignment methods and the goodness-of-fit used tests are defined seriously by the number of elements of the studied sets.. For the very small sample size (ultra low volume) which units number doesn't exceed 25 the problem of linkages estimation

The modified scale n.a. prof. V.A. Yadov using for the theoretical distributions creation in the turbulent economics.

In the current social and economic conditions, academic and corporative practice the prospects of some variation series alignment methods and the goodness-of-fit tests line using are particularly defined by the available number of elements sets. Usually for the ultra small sample size which units nu
