Medicaid Utilization", Journal of Applied Econometrics, Vol. 12, No. 3, 1997, pp. 225-242. Column 1 is the observation number. Column 2 is the number of doctor visits. Column 3 is the number of children in the household. Column 4 is a measure of access to health care. Column 5 is a measure of health status (larger positive numbers are associated with poorer health). There are 485 observations, all from the AFDC part of the sample. These data are for use with the exercises in the book Russell Davidson and James G. MacKinnon, Econometric Theory and Methods, New York, Oxford University Press, 2004.
