Abstract
Both registers and sample surveys can contain measurement error. While
some errors are invisibly present, others become visible when logical
relations in the data are investigated. When a variable is measured in multiple
datasets within a combined dataset, we can get an indication of the errors
which are invisibly present within the separate datasets. We propose a new
method (MILC) based on latent class modelling that estimates the number of
measurement errors in the multiple sources, and simultaneously takes
impossible combinations with other variables into account. We then use the
latent class model to multiply impute the latent “true” variable. Whether
MILC can be applied depends on the entropy R2 of the LC model and the
type of analysis you are interested in.
