I have the variable(s) ivfio from xwaveid merged into my master dataset (indresp) in both long and wide formats.
In terms of when I change the xwaveid data into the long format and merge it to the master (so that the variables b_ivfio, c_ivfio, d_ivfio become a single variable) what I just get when I tabulate wave and ivfio is just full, proxy and telephone interviews.
e.g.
tabulate wave ivfio
gives us:
wave of BHPSUS full inte proxyint Total
W1 2010/11 1,964 54 2,018
W2 2011/12 1,805 62 1,867
W3 2012/13 1,700 38 1,738
On the other hand when I simply merge in the xwaveid data (in its wide format) to the master and i tabulate wave by each of the ivfio's e.g. tabulate wave b_ivfio , I get for the current wave (_b) the full and proxy interviews as well as subsequent waves with other reasons e.g
tabulate wave b_ivfio (wave b is wave one)
gives us:
wave of BHPSUS full inte proxy int refusal other non moved ill/away youtint youth non refusal/n Total
W1 2010/11 1,964 54 0 0 0 0 0 0 0 2,018
W2 2011/12 1,765 16 6 24 3 5 31 4 9 1,868
W3 2012/13 1,605 14 5 25 1 3 67 7 5 1,736
I dont really understand what the ones in the wide format mean - in wave 2, the wave b variable has 1,765 full interviews, 6 refusals etc.
Getting to the point.... I want to identify those who drop out and those who rejoin.
How do I use this ivfio variable to do that? I think I use the long formatted merge? Then to get the drop outs what do I do?
Many thanks,
