Oransal ve Çarpımsal Tahmin Ediciler

Abstract

Bu çalışma, son yıllarda önerilen oransal tahmin edicileri istatistiksel olarak incelemekte ve oransal tahminin özel bir türü olan çarpımsal ve oransal-çarpımsal tahminler ile ilgili temel bilgiler vermektedir. Ayrıca, yapılan bir uygulama ile oransal tahmin ediciler duyarlılıkları açısından karşılaştırılmaktadır.

Keywords

Oransal Tahmin, Çarpımsal Tahmin, Oransal-Çarpımsal Tahmin, Duyarlılık
