Methodology of capture-<strong>recapture</strong> analysis<br />
data lead to poor capture-<strong>recapture</strong> outcomes. 7,10 Dependence of sources is often a<br />
problem <strong>in</strong> epidemiological capture-<strong>recapture</strong> applications. Such dependence can result<br />
from co-operation between the agencies that keep the different registrations, exchange of<br />
<strong>in</strong>formation or a more or less predictable flow of patients along various <strong>in</strong>stitutions due<br />
to referral. The probability of ascerta<strong>in</strong>ment by any particular source should be equal but<br />
<strong>in</strong> epidemiological sett<strong>in</strong>gs often it is not, due to the <strong>in</strong>tr<strong>in</strong>sic nature of human variation,<br />
e.g. socioeconomic differences or variation of severity of disease. Also human<br />
populations are rarely closed.<br />
It has been argued that estimates from capture-<strong>recapture</strong> studies <strong>in</strong> epidemiology<br />
are wholly unreliable unless supported by a wide variety of sensitivity analyses, and by<br />
careful medical and social discussion of variability between <strong>in</strong>dividuals, and the reasons<br />
why a particular <strong>in</strong>dividual may fail to be recorded <strong>in</strong> a particular register. Match<strong>in</strong>g of<br />
only two registers has even been called “mostly an exercise <strong>in</strong> self-deception, an<br />
unscientific, uncritical act of faith <strong>in</strong> the absolute truth of untested and implausible<br />
assumptions”. 10 Also for the application of multiple-source log-l<strong>in</strong>ear estimators for any<br />
particular observed data on real populations some claim that “<strong>in</strong> no sense there is any<br />
proof or re-assurance that this results <strong>in</strong> a valid estimate, or even necessarily produces an<br />
estimate closer to the true value than some alternative approach”. 7 Although many<br />
apparently successful capture-<strong>recapture</strong> studies have been published, only few have been<br />
reported to have failed and confidence <strong>in</strong> the validity of capture-<strong>recapture</strong> results may<br />
reflect publication bias <strong>in</strong> favour of successful capture-<strong>recapture</strong> studies rather than the<br />
<strong>in</strong>herent strength of this methodology. 47<br />
