In there I say &#8220;These methods can apply to any \u201conce only\u201d event, not just death. Frailty analysis is a related set of methods to handle censored data where the event can happen more than once, e.g. having a psychological crisis, having a baby, self-harming. Both methods are seriously underused in research into psychological issues which is so often short term or with only very limited follow-up period. Sadly, this partly reflects how little money is spent on psychological issues and therapies.&#8221;<\/p>\n\n\n\n<p>That&#8217;s it!
