D  Data
  • The data set forms part of the data library of the Medical Expenditure Panel Survey (MEPS).
  • The MEPS is a longitudinal national survey that is used to yield national estimates of health care expenses.
  • During 1999, background data and data on the health expenditures of a sample of 23,565 participants were obtained.
  • The 1999 sample was stratified into 143 strata (VARSTR99) and into 460 PSUs (VARPSU99).
  • The following variables are used in the analysis.

    • VARSTR99 is the variance estimation stratum of the respondent.
    • FACTYPE is the variance estimation PSU of the respondent.
    • PERWT99F is the final design weight of the respondent.
    • TOTEXP99 is the natural logarithm of the total health care expenditure of the respondent during 1999.
    • racex is the value of a nominal variable for the race (1 for American Indian, 2 for Aluet, Eskimo, 3 for Asian or Pacific Islander, 4 for black and 5 for white) of the respondent.
    • inscov9 is the value of a nominal variable for the type of insurance coverage (1 for private, 2 for public and 3 for uninsured) of the respondent during 1999.
    • More information on the MEPS and the data are available at http://www.meps.ahrq.gov/Puf/PufDetail.asp?ID=93.
  • The data to be used are provided in the file meps.PSF in the TUTORIAL folder.
  • The first portion of meps.PSF is shown in the following PSF window.
