11. Lindley showed that fiducial probability lacked additivity, and so was not a probability measure. 12. Also, unlike the classical fiducial inference, optimality is not a part of requirement. 13. Fisher did not consider that a cogent objection to the use of the fiducial interval. 14. Indeed, counter-examples to the claims of Fisher for fiducial inference were soon published. 15. The four outer mirror fiducials as seen by the projector with the mirror at 0?and 180?/s>There are many types of fiducials . 16. There is another approach to statistical inference, namely fiducial inference, that also considers interval estimation. 17. Global fiducials are used to locate the position of all features on an individual printed circuit board. 18. Fiducial inference can be interpreted as an attempt to perform inverse probability without calling on prior probability distributions.19. Some machines are also able to measure the PCB shear by measuring a third fiducial mark on the PCB. 20. Based on the fiducial cosmological model and some assumptions, the constrains of parameters can be calculated and confined.
