One could abstract a random sample of medical records and use that abstraction to develop an algorithm to infer the data [ 35].
In this first step – making abstraction of the eventual sample selection bias – we compare the adjusted R-squared from a binomial probit estimation of Eqn. (1), with and without including the set of dummies for the type of mismatch between the education level and the occupational attainment in the last job held in the home country twelve months prior to immigration.
Across both geographical sites, double data abstraction of a 5% sample of hospital data (dates of referral, first appointment, diagnosis and stage) confirmed an acceptable level of agreement (>80% for dates; >90% for diagnosis and stage).
