The discrepancy function is a continuous function of the elements of S, the sample covariance matrix, and Σ(θ), the "reproduced" estimate of S obtained by using the parameter estimates and the structural model.
In mathematics, discrepancy theory describes the deviation of a situation from the state one would like it to be in. It is also called the theory of irregularities of distribution . This refers to the theme of classical discrepancy theory, namely distributing points in some space such that they are evenly distributed with respect to some ...

A fundamental test of fit used in the calculation of many other fit measures. It is a function of the discrepancy between the observed covariance matrix and the model-implied covariance matrix. Chi-square increases with sample size only if the model is detectably misspecified. [33] Akaike information criterion (AIC)
Geometric discrepancy theory [1] is a sub-field of discrepancy theory, that deals with balancing geometric sets, such as intervals or rectangles.The general research question in this field is: given a set of points in a geometric space, and a set of objects in the same space, can we color each point in one of two different colors (e.g. black and white), such that each object contains roughly ...
The goodness of fit of a statistical model describes how well it fits a set of observations. Measures of goodness of fit typically summarize the discrepancy between observed values and the values expected under the model in question.
The discrepancy is called the Hubble Tension. The observations by Webb, the most capable space telescope ever deployed, appear to rule out the notion that the data from its forerunner Hubble was ...
The self-discrepancy theory states that individuals compare their "actual" self to internalized standards or the "ideal/ought self". Inconsistencies between "actual", "ideal" (idealized version of yourself created from life experiences) and "ought" (who persons feel they should be or should become) are associated with emotional discomforts (e.g., fear, threat, restlessness).
