Can I Use a Panel? Panel Conditioning and Attrition Bias in Panel Surveys

Panel surveys go mobile

In order to take panel surveys into the ‘mobile age’, a careful analysis of their characteristics is conducted. Core issues of mobile surveys and panel designs are addressed and contrasted to their respective alternatives. Moreover, the use of mobile technology for carrying out panel surveys is discussed. Thereby, necessary actions and actors involved are identified, which provides a guideline ...

An Analysis of Sample Attrition in Panel Data: the Michigan Panel Study of Income Dynamics

An Analysis of Sample Attrition in Panel Data: Michigan Panel Study of Income Dynamics By 1989 the Michigan Panel Study on Income Dynamics (PSID) had experienced approximately 50 percent sample loss from cumulative attrition from its initial 1968 membership. We study the effect of this attrition on the unconditional distributions of several socioeconomic variables and on the estimates of severa...

Introduction to Panel I

Panel Conditioning in the General Social Survey.

Does participation in one wave of a survey have an effect on respondents' answers to questions in subsequent waves? In this article, we investigate the presence and magnitude of "panel conditioning" effects in one of the most frequently used data sets in the social sciences: the General Social Survey (GSS). Using longitudinal records from the 2006, 2008, and 2010 surveys, we find evidence that ...

Kochukhov: The Doppler imaging problem is intrinsically ill-conditioned. It is not correct to characterize this problem by the number of unknowns. We are using regularization, and regularization effectively introduces a set of additional equations which smoothes the map in our case; in the case of the maximum entropy method, it selects an image with maximum entropy. So actually if I count equat...
