CovarianceEstimatorFunction is an option for generalized linear model fitting functions that specifies the estimator for the parameter covariance matrix.
CriticalSection[{var_1, var_2, ...}, expr] locks the variables var_i with respect to parallel computation, evaluates expr, then releases the var_i.
Cubics
(Built-in Mathematica Symbol) Cubics is an option for functions that involve solving algebraic equations, that specifies whether explicit forms for solutions to cubic equations should be given.
DegreeGraphDistribution[dlist] represents a degree graph distribution with vertex degree dlist.
Element
(Built-in Mathematica Symbol) Element[x, dom] or x \[Element] dom asserts that x is an element of the domain dom. Element[{x_1, x_2, ...}, dom] asserts that all the x_i are elements of dom. Element[patt, ...
EventLabels is an option to CandlestickChart, KagiChart, and similar functions that specifies events to labels.
