)))))))))))))))))))))))))))))))))))))))))))))))))))))))))) The 2002 Census of Agriculture adjusted for whole-farm nonresponse by dividing the potential farms on its list into size classes and then weighting the respondents within each class to account for the nonrespondents. Unfortunately, to assign the size-class memberships, a consistent measure of size was needed for all potential farms not ...

Abstract The IPP’s Import and Export Price Index Surveys provide estimates of the change in prices of goods and services purchased by U.S. residents from foreign merchants or sold to foreign buyers by U.S. residents. In order to meet new Office of Management and Budget (OMB) standards and guidelines for statistical surveys, research was conducted using a three-phase approach to assess the effec...

Telephone surveys face more and criticism because of decreasing coverage increasing costs, the risk producing socially desirable answers. Consequently, survey administrators consider switching their to web mode, although mode is susceptible item nonresponse. Still, we do not know whether this true for all question types. In article, analyze what extent nonresponse depends on characteristics suc...

Bias because of nonresponse in surveys is difficult to assess since information about nonresponders is rarely available. Models of nonresponse are often used to estimate the bias, but they all have assumptions about the relationship between the modeled variables and the nonresponse process. Sensitivity analysis can help explore the potential impact of the different assumptions. This study looks...

BACKGROUND Predicting rTMS nonresponse could be helpful in sparing patients from futile treatment, and in improving use of limited rTMS resources. While several predictive biomarkers have been proposed, few are accurate for individual-level prediction; none have entered routine use. An alternative approach in pharmacotherapy predicts outcome from early response; patients showing minimal (e.g., ...

1.Introduction Large national sample surveys often use sample designs to cover the complexity of study objectives. Sample weights based on the features of the sample design are often incorporated into calculations to generate population estimates. The most common components of the sample weight are the base weight that reflects the different probabilities of selection and nonresponse adjustment...

Even when researchers using mail surveys go to great lengths to maximize response rates, there will always be some portion of the intended sample that does not respond, either at all, or sufficiently -completely to allow inclusion in the estimating sample. This paper examines nonresponse and its apparent consequences for a survey of water-based recreational participation conducted in the Northw...
