The data used in this article are extracted from the March 1999 Supplement to the US Current Population Survey. There are 20871 observations and 10 variables: Variable | Mean Std. Dev. Min Max Definition ---------+-------------------------------------------------------------------- LFP | .7282833 .4448553 0 1 =1 if Working EDUC | 1.368372 .2850031 0 2.2 Yrs of Schooling/10 EXP | 2.29805 1.14609 -.4 5.9 Yrs of Potential Work Experience/10 BLACK | .0589814 .2355955 0 1 =1 if Race is Black HISPANIC | .139955 .3469486 0 1 =1 if Ethnicity is Hispanic KIDSLT6 | .3156533 .6342892 0 6 No. of kids under age of 6 KIDS618 | .706866 .9976159 0 8 No. of kids 6-18 yrs old INCOME | 5.286847 5.232533 .09 55.75 Non-Labor Income in $10,000 HHI | .4741028 .4993408 0 1 =1 if Wife Covered by Husb's HI NC | .4351493 .4957884 0 1 =1 if Region is North or Central US There are 4 zipped files. lfpw.zip : Contains the data. brq-win-lib.zip : Contains an Splus for Windows Library that estimates Binary and Smoothed Binary Quantile Regressions. brq-code.zip : Contains the original S and FORTRAN code for the estimation of Binary and Smoothed Binary Quantile Regressions. stataprogs.zip : Contains STATA code for the estimation of Generalized Heteroskedastic Logit and the Klein and Spacy (1993) Semiparametric Likelihood estimator. Since the files in brq-code.zip are intended for use on Unix systems, they are in Unix format. All other files are in DOS format. Unix users should use "unzip -a" when unzipping lfpw.zip, brq-win-lib.zip, and stataprogs.zip.
