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.

ok you are trying to say that confidence limit will be either 95% or 99% nd fiducial limits are also applicable in conventional confidence limits where value can go beyond 110% nd in this case fiducial is better than confidence limits, as its value lies bw 95% or 99% . Sir i am right na...??
