DispersionEstimatorFunction is an option for generalized linear model fitting functions that specifies the estimator for the dispersion parameter.
Equivalent[e_1, e_2, ...] represents the logical equivalence e_1 \[DoubleLeftRightArrow] e_2 \[DoubleLeftRightArrow] ..., giving True when all of the e_i are the same.
EventLabels is an option to CandlestickChart, KagiChart, and similar functions that specifies events to labels.
ExpressionCell[expr] gives an expression cell that can appear in a Mathematica notebook. ExpressionCell[expr, " style"] gives an expression cell with the specified style.
Hold
(Built-in Mathematica Symbol) Hold[expr] maintains expr in an unevaluated form.
ImageFilter[f, image, r] applies the function f to the range r neighborhood of each pixel in each channel of image.
ImageKeypoints[image] finds key features in image and returns their coordinates.ImageKeypoints[image, prop] gives the specified property prop for each keypoint.
Implies
(Built-in Mathematica Symbol) Implies[p, q] represents the logical implication p \[DoubleRightArrow] q.
