1 independent version of associated random variables
независимый вариант ассоциированных случайных величин ^говорят, что случайные величины (b1, b2,..., bk) образует независимый вариант ассоциированных случайных величин (a1, a2, …, ak), если случайные величины (a1, a2, …, ak) являются взаимно независимыми и при каждом i не меньше 1 и не больше k случайные величины a1 и b1имеют одинаковое распределение); см. associated random variablesАнгло-русский словарь промышленной и научной лексики > independent version of associated random variables

2 associated random variables
pl.ассоциированные случайные величины (случайные величины из множества действительных чисел называются ассоциированным ми, если математическое ожидание E[f(a)f(b)] не меньше произведения математических ожиданий E[f(a)]×E[f(b)] для всех неубывающих отображений f,g из K-мерного евклидова пространства в множестве действительных чисел, для которых указанные математические ожидания существуют; примером ассоциированных случайных величин являются независимые случайные величины, которые всегда являются ассоциированными); см. также association properties; independent version of associated random variables; random variableАнгло-русский словарь промышленной и научной лексики > associated random variables
