The fade away effect of initial nonresponse bias in regression analysis

Autor: Alho, Juha, Rendtel, Ulrich, Khan, Mursala

High nonresponse rates have become a rule in survey sampling. In panel surveys there occur additional sample losses due to panel attrition, which are thought to worsen the bias resulting from initial nonresponse. However, under certain conditions an

The Fade-Away Phenomenon of Initial Non-response Bias in Panel Surveys

Autor: Khan, Mursala

In practice, almost every survey suffers from the problem of non-response. The problem of non-response arises mainly due to the refusal of the persons to respond, and sometimes when there is unavailability of some persons, households, firms because o
