a

The first row shows results for the error-prone model without validation data. This would represent the model with only multiplex data.

b

The covariates W1–W5 include validation data and represent the five of 100 covariates that may be corrected. These columns show the bias (MSE) for each of the individual estimates.

c

This column represents the MSE for all 100 covariates.
