Reflection on modern methods: Calculating a sample size for a repeatability sub-study to correct for measurement error in a single continuous exposure
Morgan, Katy E; Cook, Sarah; Leon, David Adrew; Frost, Chris (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-23)Using a continuous exposure variable that is measured with random error in a univariable linear regression model leads to regression dilution bias: the observed association between the exposure and outcome is smaller than it would be if the true value of the exposure could be used. A repeatability sub-study, where a sample of study participants have their data measured again, can be used to correct ... -
