This data set gives the number of doctor visits in the last three
months for a sample of German male individuals in 1994. The data set
is taken from Riphahn et al. (2003) and is a subsample of the German
Socioeconomic Panel (SOEP). In contrast to Riphahn et al. (2003) only
male individuals from the last wave are considered. See Jochmann
(2013) for further details.
