Luiz Paulo Fávero, Patrícia Belfiore, in Data Science for Business and Decision Making, 2019 3.3.2.3 Histogram A histogram is a vertical bar chart that represents the frequency distribution of one quantitative variable (discrete or continuous). The variable values being studied are presented on the...
In subject area: Computer Science Histogram difference refers to a measure used in computer science to detect similarity between images by comparing changes in the weighted color histogram of the images. It is less sensitive to subtle motion and can be used to limit distortion caused by noise and...

A histogram is one of the most commonly used graphs to show the frequency distribution. As we know that the frequency distribution defines how often each different value occurs in the data set. The histogram looks more similar to the bar graph, but there is a difference between them. The li...
In this paper we consider how to use histograms to improve the join processing in tem-poral databases. We deene histograms for temporal data and present two temporal join algorithms that make use of this histogram information. The rst is a tem-poral partition-join with dynamic buuer allocation...
Histograms of discrete variables Specify histogram's discrete option when you wish to treat the data as discrete—when you wish each unique value of the variable to be assigned its own bin. For instance, in the automobile data, mpg is a continuous variable, but the mileage ratings have been...

In grouped data, the estimation of the Lorenz curve without taking into account the within-class variability leads to an overestimation of the curve and an underestimation of the Gini index. We propose a new strictly convex estimator of the Lorenz curve derived from a linear interpolation-based ...
