ЧТО ОЗНАЧАЕТ СЛОВО CHI-SQUARE TEST
Чи-квадрат
Тест на хи-квадрат, также называемый хи-квадратным тестом или тестом, представляет собой любой статистический тест гипотезы, в котором распределение выборки тестовой статистики является распределением хи-квадрат, когда нулевая гипотеза истинна. Также считается, что критерий хи-квадрат - это тест, в котором это асимптотически верно, что означает, что распределение выборки может быть сделано, чтобы приблизить распределение хи-квадратов настолько, насколько это необходимо, сделав размер выборки достаточно большим. Некоторые примеры тестов на хи-квадрат, где распределение хи-квадратов справедливо только: ▪ тест хи-квадрат Пирсона, также известный как тест на квадрат с квадратным квадратом, или тест на квадрат в квадрате для независимости. Когда хи-квадрат тест упоминается без каких-либо модификаторов или без другого исключающего контекста, обычно это испытание. ▪ Коррекция Йетса для непрерывности, также известная как хи-квадрат Йетса. ▪ Чик-квадрат Cochran-Mantel-Haenszel.
