چکیده
This paper summarizes the major findings from a nonresponse bias analysis of the Early Childhood Longitudinal Study, Kindergarten Class of 1998-99 (ECLS-K) first grade data. The analysis examines the potential for bias in estimates from the ECLS-K due to attrition (nonresponse) between the base year (rounds 1 and 2) and first grade (rounds 3 and 4). This work builds on a base year nonresponse bias analysis (Brick and Bose, 2001).

متن کاملEstimating Variance of the Sample Mean in Two-phase Sampling with Unit Non-response Effect
In sample surveys, we always deal with two types of errors: Sampling error and non-sampling error. One of the most common non-sampling errors is nonresponse. This error happens when some sample units are not observed or viewed but they do not answer some of the questions. The complete prevention of this error is not possible, but it can be significantly reduced. The non-response causes bias and ...
متن کاملImpact of Nonresponse on Medicare Current Beneficiary Survey Estimates
The Medicare Current Beneficiary Survey (MCBS) has been used by policymakers and research analysts to provide information on a wide array of topics about the Medicare Program. Nonresponse bias is potentially one of the most important threats to the validity of the estimates from the MCBS. In this article we present results of our methodological study that analyzes the impact of nonresponse on M...
متن کاملTesting A New Attrition Nonresponse Adjustment Method For SIPP
1. Introduction While unit or questionnaire nonresponse can seriously degrade the quality of any survey, nonparticipation is particularly threatening to a longitudinal survey like the U.S. Census Bureau's Survey of Income and Program Participation (SIPP).
