Hi Reduced, since the calendar is stored as a string variable, for it to be useful in survival analysis, it should be transformed so that each event is its own line (at least in my mind, that is how I think about it). Like I said earlier, I'm sure there's a more elegant way of separating the parts than what I did. I use Excel a lot when I'm managing data, especially for repetitious work, because I'm too lazy and impatient to do it manually.

Re: the panel question. In a sense it is a type of panel, in that births are nested within women. You can do survival analysis using the same data with the same long structure too. Of course creating this sort of "panel" is is only appropriate in some settings, i.e. when recall is reasonably accurate. I assume that recall of birth hx is generally accurate, especially if it happened in the past 5 years.
