Cervical cancer valiation data


Additionally to the main study sample (see cervical), validation data are available that give information on how likely physicians from different countries are to identify and correctly report a true cervical cancer death. In that study, a sample of physicians in each country completed a death certificate for one specific patient who had died of cervical cancer and the number of correct death certificates in each country was recorded. Validation data are therefore available on country level but provide no information on the reporting probability specific for age.




A data frame with 4 rows and 6 variables:


number of correct death certificates in each country in the validation sample


size of validation sample in each country


factor variable of European countries

W.1, W.2, W.3

predictor variables for country effects using dummy coding (i.e. England, France, Italy)


Belgium is used as the reference category.
