95% fiducial limits
Intervalle de confiance à 95 %

Ca doit avoir la même signification que Confidence limit ou Confidence interval.

disagree  Daryo: yes, the basic meaning is similar but it's used only in a specific context - so there is a very good reason NOT the use the same general purpose term.

Confidence limits (95% or 99%) are calculated either for mean and proportion. In either case the underlying distribution is Normal when sample size is adequately large. Fiducial limts is applicable only in the case of lethal dose required for 50% mortality(LD50) or 90% mortality (LD90). The underlying distribution is logistic growth or S-shaped curve. Even though we transform the data (% values into probit and dose values into logdose) to fit a linear regression equation (Y(probit)=a+b*logdose), the upper limit of conventional confidence limits may be beyond the value (say 110%), which is not true in the case of logistic growth. In such situations Fiducial limits is more appropriate than confidence limits.

If we calculate 95% confidence limits for mean or proportion, the interpretation is that we can be 95% confident that the true mean or proportion at population level will lie between lower limit and upper limit of confidence limits. Therefore, the more samples will give us narrow margin of confidence limits. In the similar way, when we calculate 95% fiducial limits for LD50, the interpretation is that with 95% confident the required lethal dose to achieve 50% mortality in the study population species will be within the lower limit and upper limit.
