Measurement error arises when the observed data deviate from true values due to inaccuracies in measurement processes, potentially leading to biased estimates and ...

Assessment of the effects of measurement error is challenging in part because the distribution of true pollutant concentrations throughout the airshed cannot be known ...

When repeated measures of an exposure variable are obtained on individuals, it can be of epidemiologic interest to relate the slope of this variable over time to a subsequent response.

The BA1500 1500-Mbit/s BitAlyzer bit-error-rate (BER) tester provides detailed BER tests and points out where and when errors occur. It shows errors, block errors, and error-free interval statistics ...
