Health Economics

  • (written as Binary Variable)
    A variable that can take one of only two values: usually 1 and 0 such as 'yes' or 'no', 'well' or 'ill', 'in-patient' or 'out-patient', 'home delivery' or 'hospital delivery'. Some characteristics may be more or less continuous (such as degree of ill-health) but the data may be presented in a binary form (sick/not sick). Usually '1' indicates the presence of the characteristic in question and '0' indicates its absence.
