/********Instructions for analyzing PAT data*****************
NOTE: RAW DATA from the minutes file do not have sample weights; thus these data 
are not representative of NYC in their raw form  
Only person-level data should be used for prevalence estimate with confidence interval
using the code and variables from the survey or accelerometer person level files


TO GET CONFIDENCE INTERVALS AND PREVALENCE ESTIMATES YOU CAN ADD THE 
VARIABLES WT_PATW2ACCEL strata_pat FROM THE "ACCL_PUBLIC" DATASET AND FOLLOW THE INSTRUCTIONS
LISTED IN THE CALLIN CODE FOR "ACCL_PUBLIC"
PATCID CAN BE USED AS AN ID VARIABLE ON BOTH DATASETS
