Work on the subset of the data that is just waves 1, 7, 12. Map to 1, 2, 3 and label 1, 7, 12 if necessary. Nick n.j.cox@durham.ac.uk sara khan I am writing to ask for advice regarding transition tables using long data. I have 12 waves of data and want to work out entries and exits from poverty. I have created the relevant variables using a lag of 1 period however, how would I modify this to allow me to create specific transition tables for entries and exits between wave1 and wave 7, and then wave7 and wave12 (rather than the previous period only as in the code below? ge lagpov=L.ps60 lab var lagpov "pov status, previous interview" lab val lagpov ps60 ta lagpov ps60, row col ta lagpov ps60 if wave==2, row col *DUMMY VARIABLES MARKING ENTRY TO & EXIT FROM POVERTY ge enterpov=0 if L.ps60==0 replace enterpov=1 if L.ps60==0 & ps60==1 lab var enterpov "entered poverty?" lab def enterpov 0 "stayed non-poor" 1 "entered poverty" lab val enterpov enterpov ge exitpov=0 if L.ps60==1 replace exitpov=1 if L.ps60==1 & ps60==0 lab var exitpov "left poverty?" lab def exitpov 0 "stayed poor" 1 "left poverty" lab val exitpov exitpov * * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
