Fiducial marker. A ruler used as a fiducial marker. A fiducial marker or fiducial is an object placed in the field of view of an image for use as a point of reference or a measure. It may be either something placed into or on the imaging subject, or a mark or set of marks in the reticle of an optical instrument.
Fiducial inference is one of a number of different types of statistical inference. These are rules, intended for general application, by which conclusions can be drawn from samples of data. In modern statistical practice, attempts to work with fiducial inference have fallen out of fashion in favour of frequentist inference , Bayesian inference ...
Fiducial may refer to: Fiduciary, in law, a person who holds a legal or ethical relationship of trust. Fiducial inference, in statistics, a form of interval estimation. "Fiducial line" or "fiducial edge" of an alidade, an instrument used to measure the angle to a distant object. Fiducial marker or fiducial, an object or marking placed in an ...
According to DiVincenzo's criteria, constructing a quantum computer requires that the experimental setup meet seven conditions. The first five are necessary for quantum computation: A scalable physical system with well-characterized qubit. The ability to initialize the state of the qubits to a simple fiducial state.
Fiducial inference utilizes a data set, carefully removes the noise and recovers a distribution estimator, Generalized Fiducial Distribution (GFD). Without the use of Bayes' Theorem, there is no assumption of a prior, much like confidence intervals. Fiducial inference is a less common form of statistical inference.

Statistical inference is the process of using data analysis to infer properties of an underlying distribution of probability. [1] Inferential statistical analysis infers properties of a population, for example by testing hypotheses and deriving estimates. It is assumed that the observed data set is sampled from a larger population.
It so happened that, somewhat earlier, Fisher published his first paper [13] concerned with fiducial distributions and fiducial argument. Quite unexpectedly, while the conceptual framework of fiducial argument is entirely different from that of confidence intervals, the specific solutions of several particular problems coincided.
