Abstract

The power function of the one-tailed T-test is characterized by a rapid rise from close to zero for < PO to one as becomes larger thanUo. The larger the number of elements in a simulated sample, the faster the power rises to
one, apparently until the mean value theorem takes effect and the sample averages begin to take on a normal distribution themselves which gives a limiting power function where all of the assumptions of the test are satisfied

Simülasyonlarla Tek-Yönlü T-testi'nin Güç Fonksiyonunun Elde Edilmesi

Abstract

Tek yönlü U < PO T-testinin gÜç fonksiyonu siflra yakinken u degeri PO de5erini astikça bire htzla yakla;an bir fonksiyon olarak karakterize edilebilir. SimOlasyondaki birim sayist arttlkça, gÜç bire daha hull yaklastr. Bu durum ortalama deäer teoremi etkisini gösterinceye ve örnek ortalamalart normal daäthrn seklini ahncaya kadar devam eder ki bunun ötesinde zaten test için gerekli varsaylmlar otomotik olarak sa§lanm IS olur.
