Additionally to the main study sample (see
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
predictor variables for country effects using dummy coding (i.e. England, France, Italy)
Belgium is used as the reference category.
