Although Internet technology provides significant opportunities for innovation in survey design, systematic research has yet to be conducted on how most of the possible innovations might affect measurement error, leaving many survey designers "out in the cold".
Confounder measurement error leaves residual confounding that may have a substantial impact on the estimated effect of correlated covariates.
His errors left him in 15th place.
By doing so, the only source of error left was the direct measurement of the fractured side.
To assess the measurement error, the (SD left( {text{e}} right) {text{and}} CoVleft( {text{e}} right)) of the property values having same soil type and depth were determined.
It should be noted that the assumptions about the distribution of the error terms in the model leave the covariance matrix of the measurement errors to be estimated, as these are the parameters of interest in this case.
To determine the measurement errors in our dataset, 20 participants were scanned and rescanned after shortly leaving the scanner.
Stratifying by ENM and cell line, the CPPs found that both error in mean and measurement error were either reduced or left unchanged when comparing phase I with phase II data.

This assignment may lead to some measurement error in the school-leaving variables and the direction of the bias attributable to measurement error is difficult to sign (Bound et al. 2001).
