| Abstract: | To examine nonresponse effects on variable relationships, datafrom a panel study of 1,870 older Iowa residents are reported.When data are accumulated by wave of response, differences areminor on variable distributions (percentage, mean, standarddeviation), bivariate relationships (correlation), and multivariaterelationships (regression), suggesting that the assumed impactof nonresponse bias on variable relationships has been overstated. |
