Here are the modeling functions for producing an NMMAPS like single
city analysis. The functions are SPLUS code and were run under Sun
Solaris 5.8 using SPLUS 3.4 and 6.1. Data is assumed to be in the
canonical form given in the iHAPSS Data section.
The main function is DLmodel found in support.s.
Given the appropriate data this function will estimate either a
distributed lag model or singlepollutant model. The file basic.s
contains an example where an estimate for a single pollutant is
obtained for Chicago. See the references at the top of
basic.s for details of the NMMAPS model.
OzoneDL.s contains code for running a constrained distributed lag
model for summer data in 95 U.S. cities. The distributed lag example
given here was used in estimating summer ozone effects for the paper
"Ozone and mortality in 95 U.S. cities, 19872000". See the
reference at the top of OzoneDL.s for details.
