Abstract
The effect of measurement errors in covariates in the Cox
regression model with time-fixed covariates was discussed by Prentice
(Biometrika, 1982). These results will be briefly reviewed and extended
to the situation where updated recordings of a time-dependent covariate
are available. Here, both measurement errors and ageing of the available
covariate values play a role and these effects are illustrated using both
real and simulated data. Finally, methods for adjusting for these effects
in the analysis are discussed.
